Create a new color from two RGB values

Is it possible to combine two RGB values to create another color in livecode?

Example:

First color: (0,0,255) //BLUE

Second color: (255,0,0) //RED

In this case, I would like to store the result of the two colors into a variable.

Let's say, put "0, 0, 255" + "255, 0, 0" into CombinedColors

It isn't exactly clear how you want to combine the colours. If you want to blend the colours, you might simply add them.

put 255,0,0 into myRed
put 0,0,255 into myBlue
put 0,10,100 into myGreen
repeat with x = 1 to 3
  put min(item x of myRed + item x of myBlue + item x of myGreen,255) into \
    item x of myNewColor
end repeat

The formula I'm using here doesn't make much sense. If you can more specific in your question, I'll be able to adjust my answer with a better formula.

You may also use weighted values:

put min(.333*item x of myRed + .333*item x of myBlue + .334*item \
        x of myGreen,255) into item x of myNewColor

You can adjust the weights to make the blend appear more natural. (This example is with 3 colours, to demonstrate the weights).

For combining 2 colours using RGB values, there are 2 ways.

  1. If you need a lighter texture, the formulae you need to use is (r1, g1, b1) + (r2, g2, b2) = (min(r1+r2, 255), min(g1+g2, 255), min(b1+b2, 255))

  2. If you need a slightly darker texture , use (r1, g1, b1) + (r2, g2, b2) = ((r1 + r2) / 2, (g1 + g2) / 2, (b1 + b2) / 2)

Or if you just want to avoid the hassle , use this simple online tools http://meyerweb.com/eric/tools/color-blend/
