Hi Ayse,

Try:
Change type to RGB and use Image-->Color-->Split Channel
Fill the whole 'red' image with red (Select All-->Fill (with red selected as fill color))
Merge the three images again Image-->Color-->Merge Channels

And you should get a red image with white selections.

Hope it works

Dear Arne,

thanks for that -- my one problem is that no matter what I choose, black areas become coloured, but the areas that were once white now turn black (or coloured if I invert the image). Is there a way to have all the black pixels red for example, but keep the white pixels white?

sorry if this seems basic, I tried every variation of the LUT but none of them seem to work for me

regards

Ayse
