Android Question How can I mix RGB colors ?

[sibutr]

I need to mix 2 or 3 RGB colors in B4A ?

Red + Green = ? ( Yellow )

button1.color and button2.color makes button3.color

Colors.ARGB.

Button.Color is write only.

you can mixing the colors like this

Sub mixColors(col1 As Int, col2 As Int) As Int
    Dim r1, g1, b1, r2, g2, b2, r3 ,g3, b3 As Int

    r1 = Bit.UnsignedShiftRight(Bit.And(col1, 0xff0000), 16)
    g1 = Bit.UnsignedShiftRight(Bit.And(col1, 0xff00), 8)
    b1 = Bit.And(col1, 0xff)

    r2 = Bit.UnsignedShiftRight(Bit.And(col2, 0xff0000), 16)
    g2 = Bit.UnsignedShiftRight(Bit.And(col2, 0xff00), 8)
    b2 = Bit.And(col2, 0xff)

     r3 = (r1 + r2)/2
     g3 = (g1 + g2)/2
     b3 = (b1 + b2)/2

    Return Colors.RGB(r3, g3, b3)
End Sub
