How To Pick The Right Colour Schemes For Your Visual Aid

Colour is a powerful tool in visual aids. It is one of the elements of designs that I talked about in my post How to Create Effective Visual Resources - Part 1: Elements of Design. In the post, I mentioned different colour schemes that can be used, however did not describe them in detail but have saved that for this post. 

To understand the colour schemes, we first need to cover the primary, secondary, and tertiary colours. This is all part of what we call colour theory.


Primary Colours

The primary colours are yellow, red, and blue. These hues can not be attained by mixing other colours. However, they can be used to create secondary and tertiary colours. 


Secondary Colours

The secondary colours are colours that are created by mixing two primary colours together. Since there are only three primary colours, there can only be three mixed combinations that create three new colours. These colours are orange (created from mixing red and yellow together), green (created from mixing blue and yellow together), and violet (created from mixing red and blue together).


Tertiary Colours

The tertiary colours are colours that are mixed with one primary colour and one secondary colour. These include yellow-orange, yellow-green, blue-green, blue-violet, red-violet, and red-orange. 


Intensity

Intensity, saturation and chroma. These words can be used interchangeably to describe the brightness of a hue. To change the intensity of a colour, you generally mix it with it's complimentary colour. As more and more of the complementary colour is added to the original colour it will become duller and muted. This is where the term earth tones might sound familiar. 


Now that we have covered some colour theory, let us get into the colour scheme! 


Colour Schemes

Warm & Cool Colour Schemes

Warm and cool colour schemes are often used to convey a feeling or mood. A warm colour scheme is composed of reds, oranges, and yellows. A cool colour scheme is composed of blues, greens, and violet. 

 

Complementary

A complementary colour scheme is made up of a pair of hues (colours) that are opposite on the colour wheel. Some examples are green and red, yellow and violet, and blue and orange. You see these all around you and you may not realize it! Just think of two big holidays, Christmas and Easter. What colour scheme is mainly associated with each of these holidays? If you answered re and green for Christmas, and yellow and violet for Easter, you are correct!


Split Complementary

A split complementary colour scheme is similar to a complementary colour scheme. The difference is that instead of choosing two colours that are opposites, you choose one colour and the colours on each side of its complementary colour on the colour wheel. Like the example shown, this could be violet with yellow-orange and yellow-green, instead of yellow.

Triadic

A triadic colour scheme is when you draw an equalitarian triangle on the colour wheel. The corners of the triangle will land on three different colours, creating a colour scheme. Examples could be as simple as the primary colours or secondary colours as they are both sets that have their colours equally spaced from each other. Using the primary colours as a triadic colour scheme is very common in school materials. There are also countless examples of triadic colour schemes that can be found in nature.



Tetradic

Similar to the triadic colour scheme, the tetradic colour scheme uses a shape to determine its palette. In this case, we use a rectangle instead of a triangle. To create this palette, you pick two colours besides one colour. This means that you will either pick two tertiary colours or one primary colour and one secondary colour. To complete the rectangle, you select their opposites on the colour wheel. In the end, you always end up with two sets of complementary colour schemes. 



Analogous

An analogous colour scheme is when you use three or more colours that are beside each other on the colour wheel. An example is violet, red-violet, and red. Analogous colour schemes are commonly used and seen in room decorating, websites, and brochures. 



Monochromatic & Monochrome

Something to keep in mind is that monochromatic is different from monochrome. Monochrome means having just one colour while a monochromatic colour scheme uses any shade, tint, tone, and intensity of just one colour. This means that there are more hues in a monochromatic colour scheme then there are in a monochrome scheme. Monochromatic colour schemes can create beautiful visuals, especially if you are teaching kids about colour. A monochrome visual may be appropriate when you want kids to colour outlined shapes or images.

As a word of caution, when teaching kids with disabilities, it is often better to simplify visuals. This means using a monochromatic colour scheme can be confusing to them. Using black and white images especially can hinder their learning. 


Take Away

Hopefully, you now have a better understanding of colours and how combining them in different colour schemes could make an impact. No matter the visual, there is always a scheme that will work best!

5 Useful Types of Visual Aids

Are you still unsure what some good visual aids are? In the How do visual aids help students with learning disabilities? post, we covered six different types of aids that specifically can be beneficial to teaching kids with learning disabilities. Those things included graphs and charts, peer models, photographs, graphics, videos, and objects. These are just as great for kids that don't have learning disabilities. In this post, we will cover five additional visual aids that could help in a classroom setting. These will include posters, handouts, props, presentations, and hands-on experience. Posters Posters are a great way to add colour and variety to a classroom while being educational. Common uses of posters may include calendars, task charts, infographics, maps, and diagrams. Calendars are common in elementary school classrooms. These are great when teaching kids about days, weeks, months, and years. Along with calendars, weather charts are commonly placed beside to help kids id
