Recolor Image

I am building a replacement for the TabStrip control, and am having trouble drawing my images to a custom color.
My control looks something like this where the tabs are down the left hand side.
_____
{_ |
{ | |
{ | |
|____|
These tabs are black and white images and I would like to be able to recolor these to a custom color.

I know it is simple but I cant get it to recolor the image and make the background of the image transparent. Can anyone please tell me how to do this??

Thanks

my image didn't really work

Just ignore all of the .'s

You can convert to the HSB colour scheme, then increase the saturation to 100%, and change the hue to a random number. Then you can convert it back to RGB.

Another way would be to have R, G, and B values (decimals) that you multiply by what they have, and that gives you a new colour. Eg.

VB Code:

Function Colour(R As Long, G As Long, B As Long, cR As Single, cG As Single, cB As Single)
    R = Round(R * cR)
    G = Round(G * cR)
    B = Round(B * cR)
End Function
