Filter to convert RGB pure colors to custom ABC colors?

Hey, guys.

Do you know if there is an AfterEffects filter that allows you to directly convert RGB colors from an image to other ABC colors defined by the user?

As a picture is worth a thousand words:



I would like to start from an image like the one you see above on the left (where there is a gradient between pure RGB colors) to another image where each of these channels becomes a specific color defined by the user (and can be easily and intuitively modified).

What I show you above is done in AE, in fact, but in several steps: working with 3 layers, using a combination of filters "Calculation" + "Tint", to initially convert each of the channels R, G, and B to pure white, and then tint those 3 whites with my colors A, B and C, to end up merging the 3 layers using ADD modeā€¦

I am very surprised that such a simple thing as this cannot be done in a single stroke, with a filter/effect, in the way of the filter "Tint" or "Tritone"... but no matter how much I look I can't find it...

Any idea?

Big thanks for your feedback! :-)

Ohh, YES!

Colorama did the trick!

I used lot of times Colorama, but converting from Intensity or Lightness. I hadn't realized that HUE can be used as a starting point.

Thank you so much, Oleg! :-)
