Interesting point, in relation to toilet colour. I guess we take this minor detail for granded
thus nv seems to notice….

We learn about the 12 basic colour palette, if an image is of one colour, using the colour
oppsite will adjust the intensity etc.

“Complmentary colours are oppsite from each other on the colour wheel.”
Eg. Nus orange and blue mix. But still must take note of the colour proportion though.

Glad to find this after my fruitless internet search regarding complementary colour…

Oh, interesting colour mixing flash software !!
