Below are a few more small experiments and tasks on the subject of designing with light colours and colour filters and colour mixes.
Task 1
Design two colour filters using glass paint.
Use red, green and blue glass paint to create two Plexiglas plates with different patterns. The illustrations here only examples, you are free to design your own pattern.
Next, as in the additive colour mixing experiment, you will overlap the light images on the wall through the two designed colour filters by aligning the lamps. Before you do this, make a sketch in which you guess and note, what colours the overlapped areas will have.
Check your predictions and note the colours you observe on the wall. Therefore, you turn on the lamps and observe, which colours can be seen on the wall. Note these above your predictions. Were you able to guess all colours beforehand?
Task 2
„colouring“ objects
Which colours of the glass paint do you have to use painting your colour filter, when you place it between a white lamp and the object mentioned in order to…
- colour a banana green?
- colour the Telekom logo blue?
- change a cyan-white-magenta-white striped jumper into a black-white striped one?
Create the colour filters with stained glass colours in the way you think will „colour“ the object appropriately with coloured light. Afterwards, try out your colour filter with the materials. Have you designed correctly?
Lights on!
