How do i remove a certain colour from a picture?

If you have photoshop:

Open your image in photoshop

go to the Select menu, then Colour Range, then from the drop down menu select the colour you want to remove. It may tell you 'no more than 50% pixels were selected' but just press OK.

Then go to Image menu, then Adjustments, then Hue and Saturation. Then slide the Saturation slider all the way to the left. That should remove most of the colour you picked.

I hope that helped a bit : )

I know you can scan it in and do it on Photoshop and Illustrator, but that might be a problem if you don't have either of those programs. I'm sure you can go to Kinkos though, they might be able to help you. The other option would be to get a transparency thats tinted correctly to cancel out certain colors. But I believe that would only work with red?

Use Ulead photo program. Go into the tone area and play until you get what you want.

Just click the black and white version on your photo editor.
