i have this image in photoshop below, and i am trying to figure out a way to get rid of all of the white parts of this image and replace with the same blue color that is there.

I have tried:

  • Hue / Saturation
  • Replace Color Tool

and neither seems to give me what I want.

Is there anyway to do a replace of the white streaks in this image and replace with the blue color?

do you want to keep the greys? e.g. so it is a gradient from grey to transparant? –  Luuk Oct 19 '11 at 11:24
    
Selective Color might be useful. Though, if you take the whites out of the image, it'll look very flat... –  Johannes Oct 19 '11 at 13:31

If I understand what you're going for correctly, the most expedient way would be to apply a gradient map from dark blue to light blue. I got this result with about 60 seconds of trial and error:

gradient map

The process is basically:

  • Create a gradient map adjustment layer
  • Sample the image for the blue values you want to use
  • Use them as color stops, moving the stops until the levels are about where you want them. Add as many stops as you need to achieve a wider color range with more depth. Wiggle them around until it feels right.

For reference, here is the gradient map i used

Hope that helps!

The Eliminate White filter will replace white with transparency. You may need to apply Layer > Matting > Remove White Matte after this to get the colors right. Then, you can paint or fill in what you want on a new layer behind this one.
