x=t-i?

(means answer= total-input)

i call it the inverting equation...

if you've ever been in paint and seen the "invert colo(u)r [ctrl+i] you can use this simple equation. say you have an RGB value (100,32,91).

The total for any rgb number is 255, so lets replace the letters with numbers...

(r value) x=t-i

x=255-100

x=155

and repeat for green and blue values.

(g value) x=t-i

x=255-32

x=223

(b value) x=t-i

x=255-91

x=164

Ta-da! the inverted state of ink rgb(100,32,91) is (155,223,164)!

Try it for yourself.

ps. this also works for angles. - 21 Mar '06 09:05

Max - value = remainder

I never would have come up with that.
