How are colour wheels structured? What are primary and secondary colours? The modular Connector paint tablets allow relationships between colours to be vividly represented. Which colour is still missing in the caterpillar, and which colour tablet is needed to complete the colour wheel? The vibrant gouache paints let children experiment with mixing colours in a playful way. Simply join the relevant Connector paint tablets and start mixing new colours. Secondary colours (orange, green and violet) are created by mixing two of the primary colours (red, yellow and blue) together. The unique Connector paint box is perfect for any techniques and applications that children and teachers may want to explore in class. The rich colours, easy application and high yield of these paints ensure that children are able to enjoy lasting painting fun.
