I have an image with a lot of white with intricate transparency. Basically it's like this example but white [used black background for visibility, click for more accurate example].
I want to preferably in paint.NET turn it let's say red, like how with a color image you can use the hue tool to transform anything from one color to another.
Color burn blending achieves this as seen when a background is included except that it turns the transparent parts also red.
How can I achieve an effect like the hue tool where the alpha and lightness and stuff are fully preserved like the hue tool does -- like a 50% transparent white pixel will become 50% transparent red, a 10% bright pixel stays 10% bright as the new color, etc.
