Hello -- what a superb forum. Here's my 2 questions ... is there a simple process where I can select a given color value in an image and change all other pixels within the image which have the same value to a completely different color value ? (Example : if I specify a pixel that is a certain RGB shade of blue, and I want to "convert" all other pixels with that same RGB blue value to ... say ... a certain RGB value of red ? Question 2 is like the first one, only I'm wandering if there's a way I can specify a tonal range within the image and convert all pixels within that range to either (a) a specific new RGB value or (b) a entirely different tonal range ? Please keep in the mind that the pixels can be anywhere in the image. (It's not like I'm trying to change a singular colored object within the image, but ANY and ALL pixels within the image, wherever they are situated, which meet that "color criteria".) Thanks for your help and the excellence & inspiration in this forum -- Ken

Hello Ken, The easiest way to do this is as follows: Select the Magic Wand tool (shortkey=W), now before you use it go to the Magic Wand Options screen and change the settings: - Uncheck "Contiguous" - Set Tolerance to 0 Now, when you use the Magic Wand on the pixel that has the RGB code you want to replace, it will also select all pixels in the picture that have that specific RGB code. Replacing the color with a different color is even easier now: simply make sure the NEW color is selected as background color, and press CTRL+DELETE...presto! That's it! Happy now? :) Any questions, let me know... The Engineer.

Yes Ianbush there is...but using the method I described works 10 times faster when you get the hang of it. I used to use the Select Color Range option too, while working on some Gameboy Color Graphics (where you have to be very careful with colors)...till I found out what the "Contiguous" option of the Magic Wand did...works way, way, way, WAY faster...believe me :) The Engineer.

Replace color has always worked best for myself. Way more accurate when your color needs to be dead on.

Gents, thanks very, very much for both your speedy & simple replies. I'll experiment with both Thurs. evening. All the best to you, Engineer and Spanfarkle !!! -- Ken
