Complementary Colours

As a continuation to learning about Colour we talked about Complementary Colours this week. Complementary colours are the colours that are found directly opposite each other on the Colour Wheel.


So, for example, Yellow and Violet are a complementary pair, as are Red and Green, Blue and Orange. The students learned that the complement of a Primary colour is always a Secondary colour. They also discovered that all 3 primary colours (yellow, red, blue) are present in any 2 complementary colours. Let's take Yellow and Violet again, Yellow is a primary, Violet is made up of Red and Blue, thus all 3 primary colours are present. Using this idea the students were then able to deduce what a complement of a colour would be without looking at the colour wheel. If I asked them what the complement of Orange is they know that Red and Yellow make Orange, therefore Blue is its complement as it is the only remaining primary not named yet.

Colour Charts

Grade 6 and Grade 7 have completed colour charts to use as a reference for future painting assignments. Each student was asked to make a chart using only their Primary colours (Yellow, Red, Blue) + Black and White. These five colours are all they will be working with for their next painting project and so they were asked to create a chart representing the following Hues: Yellow, Orange, Red, Violet, Blue, Green, their Shades and Tints, as well as a Greyscale.

The aim of the exercise was to teach the students how to mix their own colours successfully while they got to know the properties of their particular brand of acrylics. It also showed them in a practical manner how to determine Value (the lightness or darkenss) and Intensity (the brightness or dullness) of a Hue.
