color creation with primary and secondary colors
do this expérience, we
have need a white light as well as 6 different plastic filters which
represent the 3 primary colors which are red, blue, green as well as
the 3 secondary colors which are magenta, yellow and cyan.
this experiment shows how to create colors with the primary and secondary colors.
To create these colors we put 2 color filters in front of the light which create a new color. Let's take an example, if we put a filter of a primary color like red in front of the white light then a blue filter, when we bring together the blue and red beam we obtain a secondary color which is magenta. Then we do the same with the other primary color and we notice that its creating the secondary colors. Conversely, using the secondary colors gives the primary colors.
We notice that if we gather the beams of light from the three secondary colors we obtain black, conversely if we gather the beams of light from the three primary colors we obtain white
