I have changed the colour mixer so it works using RGB instead of HSV.
Use the colour palettes or the sliders to change each colour. The mixture of the two colours will be shown where the two colours overlap.
Use the colour balance slider to set the balance A negative number means the left colour is stronger
A positive number means the right colour is stronger
Zero means both colours are equally strong
Hold down the space key to view the colour as one circle.
How to use the sliders:
There is a sprite that senses colours.
NOTE: The colours may not be accurate.
