Using RGB Values - Results not as expected

I'm making an object where i want to texture two sides (actually a texture with text on it)

So i create the textures using gimp, with a solid background colour
I note the rgb values for the background colour, and set the colour of the prim to the same rgb values.

Then apply the texture to the required faces, and the colours don't match

The prim colour is different to the colour in the texture even though the rgb values are the same.

Am I doing something wrong??
Any suggestions on getting the colours to match?

make the colours in your gimp texture as you want them, then tinker with colour values on the prim to match is the way to go.

Make your prim all white. Setting it to a color makes it add that color to your texture.

I'd go the other way around. Set the color how you want it in SL (utilizing fullbright, at least temporarilly), and then you can eyedropper the color right into your paint program, for an exact match.

Photoshop can eyedropper color from anywhere on the screen, even from outside PS itself. If GIMP can't do that, then simply take a screenshot, paste it into an open image in GIMP, and eyedropper it from there.

You can use the eye dropper to pick a color outside GIMP too.

Thanks, Peggy. Good to know.

OK I've tried to do this and failed, can you explain how this is done? thanks.

1. Make sure at least one image is open in PS. It could be new one or a pre-existing one, doesn't matter.

2. Grab an eyedropper. This can be the actual Eyedropper tool from the toolbox, or the one in the color picker, or the one that pops up when you hold Alt with the paintbrush or paintbucket.

3. Click somewhere in the image, and then drag to somewhere else on the screen. Watch the foreground color swatch in the toolbox as you do this. Notice it's sampling color from every point on the screen that you cross as the mouse moves.

4. When you get to the spot you want to sample, let go of the mouse button.


Happy coloring.

Thank you Chosen.
