Interior Design and Architecture: Color and Design Concepts

living room design

We are constantly surrounded by colors in our daily lives—from the clothes we wear to our homes and workplaces. Colors have a powerful effect on our emotions and moods, affecting our behavior, ability to think, and perception of the world around us.

Color and Light

Color and light are interconnected. Color is perceived as light reflected from a given surface, but it is not a physical property of the object itself. It is a psychological response to light. 

We can describe colors through three dimensions: hue, value, and intensity (HVIT). 

The HVIT system works like this:

  • Hue: the primary color as defined by its wavelength; reds, oranges, yellows, etc.
  • Value: the amount of lightness or darkness in relation to white on a scale from black (0) through various shades of gray to white (10)
  • Intensity: how saturated or dulled down the color appears

Color Psychology

You might have heard the term “color psychology” before. It’s a branch of psychology that studies the effect and influence of color on human behavior and cognition. 

Color psychology is based on the belief that colors can have a powerful impact on human moods, emotions, behavior, ability to think, and perception of the world around us. For example:

  • Red is a warm color associated with the passion that can stimulate aggression or anger. It’s a good choice for rooms where you want to encourage interaction, but not in kitchens or bathrooms, which could cause stress or disharmony among family members.
  • Blue is an emotionally calming color that evokes feelings of tranquility and peace. Try using blue in rooms where you want people to feel relaxed—like bedrooms, studies, and living rooms—so they’ll be able to relax after a hard day at work or school!

Color Psychology and Interior Design

While it may seem that interior designers should be aware of the psychological effects of color on their clients, many fail to use this knowledge in their designs.

Color psychology can help you create a more practical interior design that will positively affect not only your client’s moods but also their perception of the space itself.

Using color psychology can improve your home or business’s interior design and architecture by creating an environment that effectively communicates your brand’s message while creating an enjoyable experience for those who enter it.

How does Color Theory Help in Home Design?

Color theory is the study of how colors interact with each other. Color theory helps you choose the suitable color scheme for your home, making it more appealing to the eye and enjoyable to be in.

Color is one of the most important aspects of interior design. It’s often said that color can make or break a space. If you’ve ever been in a room painted so poorly that it just feels off, you realize how true this is.

When choosing colors for your home, the understanding basic color theory will help you choose colors that work well together and look cohesive throughout your entire home.

Psychological Effects of Colors


Red is a powerful color associated with the heart, so it’s not uncommon for people to associate this color with romance and passion.

You can use red in office buildings or home offices, the living room, and the bedroom. Red is very bold, and it can help make your space look bigger by adding contrast. If you want to add more color to your room, you should try using red as an accent color.

However, it would help if you were careful when using red in your home because it can have some negative connotations (such as being associated with danger). 

So if you’re thinking about including red in your design scheme, try pairing it with another neutral like white or gray for balance.


Orange is a warm color, much like red. It inspires sexuality, desire, and appetite. Orange is also a fun color; it makes us feel happy and cheerful. Orange is a warm color because of its liveliness and playfulness. 

Orange is associated with the sun. Its warm tones are stimulating and energizing; its high visibility can be helpful in a room where you need to pay attention to detail—like a home office or kitchen. 

In modern kitchens and bathrooms where stainless steel appliances are standard fixtures, orange countertops can be an excellent choice for creating a unique look that complements existing decor. 

When used sparingly in small amounts as an accent color in rooms such as bedrooms or living rooms (especially those with wood floors), it will enhance the overall feeling of warmth without overwhelming other colors present in these areas of your home. 

A bright shade of orange on walls will make them appear taller than they are—a great trick if you want more space without having to increase square footage!


Yellow is a cheerful color that many people love. It can be used as an accent color in any room, but yellow works exceptionally well in the kitchen and dining room because it adds brightness to spaces often considered too dark or gloomy. The same goes for bathrooms, hallways, and other areas that need extra light.

While the color yellow positively affects the psyche, it may cause problems in certain circumstances. 

For example, the dull shades of yellow can instigate a feeling of doom, decay, and sickness. It is best to use bright shades of yellow around the house as they can have an optimistic effect. 

Due to this highly favorable effect, an utterly yellow room can drive up your blood pressure and make you feel energized at times when you shouldn’t be.


Green is a powerful color in interior design. It’s soothing, relaxing, and inviting. It’s also the color of nature to create a natural feeling within your home — whether you want to feel like you’re outside or just want something that looks nice and earthy.

Green is a good color for the bathroom: Green has been shown to help reduce stress levels when used as part of your decor plan. 

The calming effect may come from its association with nature or something more mysterious, but whatever the cause, using green in bathrooms can help bring down your blood pressure (and help prevent heart attacks) by reducing stress levels—just one more reason why we love this color!


Blue is among the most calming colors in the palette for interior design. Blue works well in bedrooms, offices, and kitchens. It’s also ideal for bathrooms and hallways (especially if they lead to laundry rooms).

Aquatic shades of blue such as sky blue and light blue have a healing effect on the mind. Blue has little to no adverse impact on the psyche; it is an excellent choice for bedrooms since it promotes relaxation and restores energy.


Purple is a powerful color that evokes feelings of sophistication and royalty. Purple is also associated with creativity, so it’s great for areas in your home where you want to inspire creativity, such as the bedroom or dining room.

For bathrooms, purple adds an air of luxury to any space. It can make a small bathroom look more extensive and more open due to its ability to reflect light on walls and ceilings while also giving off a calming effect by helping calm anxiety.

The color purple can feel cold and harsh when used in large amounts but still has many benefits when used sparingly in rooms like kitchens, where it has been found that reds help stimulate appetite while purples inhibit hunger pangs!


Pink is a very powerful and feminine color. It is associated with love, compassion, and romance. 

In the past, pink was considered a more appropriate color for girls than boys. However, this has changed over time as some designers have gained inspiration from nature to create their palettes of pink tones.

Pink can be used successfully in many different rooms of the house, including bedrooms, kitchens, bathrooms or living rooms, and dining rooms. 

The cool tones of light blue may be added to create a fresh feeling within these spaces while brightening up any space with its happy vibes!


Black is often associated with power and authority; it symbolizes strength, elegance, sophistication, and formality. This makes it an ideal choice for modern interior design that seeks to create an atmosphere of luxury and sophistication.

The use of black color in modern interior design has become more and more popular over the years. 

Several designers have used this color to transform dull spaces into elegant ones. They have found ways to utilize this versatile color for their purposes, such as making it appear lighter or darker depending on its application mode (light charcoal vs. dark charcoal).


Gray is a great color to use in interior design because it’s a neutral color, so it can be used to tone down other colors and create a calm atmosphere. It’s also perfect for modern design because of its simplicity and practicality (gray doesn’t show stains or dirt as quickly as other colors). 

Gray is one of the best colors to use in bedrooms because it creates an airy feeling while still warm enough to give you a good night’s sleep!


The color white has many uses in interior design, depending on the application. White is a good choice for any room that includes natural light or a great view. 

White works well with earth tones and other neutrals, so if you have wood floors, consider painting your walls white or off-white. 

The same goes for adding color through artwork and accessories: anything that can add contrast without being too bright will make your space feel more spacious.

White is also an excellent choice for a bathroom or bedroom—the extra light helps to make these rooms seem more prominent while still feeling cozy. 

A living room can also look grand with white walls; just be sure not to overwhelm yourself by using too much furniture made from dark woods or fabrics! 

If you want something less stark than plain old white (or even off-white) paint, then go with eggshell instead; it’s got enough sheen without seeming too glossy like flat paints tend to be.
