I found out that mixing the colours of paint using red, blue and green make brown.
I found out that the primary colours of light which are red, blue and green all mixed
together make a very bluish white. That happened because when I did the
experiment I didn’t have the same voltage light bulbs. If I did have lamps with all
the light bulbs of same voltage the result of the colour would have been more
brighter.
In this experiment I learnt that combining the colours red, blue and green can make
white. It depends on the format the colour comes in and the way you mix it.
Using colours from light makes a colour that is lighter.
Using colours from paint will make a colour that is darker.
