Did you know?
Do you have a tendency to associate colours with sounds, flavours, numbers or letters of the alphabet? Perhaps you're a synaesthete!
Some experiments
Mix & match
Can you recreate an exact colour? Using the measuring buttons, mix the primary colours red, green and blue or cyan, magenta and yellow to try and work out which mixture recreates the colour shown. Well done, now you know what the trichromatic theory of colour vision is! In pairs, will you be able to “mix & match” the colours faster than your opponent? Compare your results and gain awareness of the differences in our individual perceptions: for we do not all see colours in the same way.
Coloured shadows
Enter the Cave and immerse yourself in the circle of white light. Inside the circle, and depending on your position, your shadows will multiply and appear in different colours: red, green, blue, cyan, magenta, yellow and black. This is the principle of additive colour mixing, used by television screens and computer projectors and monitors, demonstrated to entrancing effect!
Dot-to-dot
Give free rein to your imagination as you create dot-to-dot light drawings using small colour cylinders. Signs, images or more abstract forms will appear, disappear, merge or adjoin as you go, creating a collective and ever-changing cave fresco. A fun and visually appealing experiment for all ages!
