Am I stupid!? Changing color does not work

Hi all!

I have an image and I want to change all colors into a different one. So what did I do:
* Select region by color
* switch to pencil tool
opacity 100
mode normal
circle big
color the new I want
and then I thought I can draw and the colors would be exchanged.

Well, instead of a nice blue I get a smeary grey, strange. Looks like instead of *replacing* the values of the pixels some combination of the pixel values is done.

I thought with opacity 100 this will not happen, but I seem to be wrong. Any idea/help???

Best wishes

Norbert

i think you are probably painting an indexed image.

change the mode to rgb using Image/Mode/RGB

you are not stupid. your image is.

If you are indeed editing an Indexed image, you may wish to leave it in Indexed Mode and open the "Dialogs->Color Map" window. This will allow you to individually change each of the colors in the image. This will be tedious if you have more than a couple dozen colors but if you have only a few (for example, a cartoon graphic), this is a quick and easy way to change the colors.
