Hi, i really LOVE Real World Paint, it instantly became one of my favorite programs, but i have a really weird problem.

If the default gamma correction is 2.2 colors look the same on the palette, on the image/editor and on other programs, but the RGB values are wrong, in fact for RWP a certain color has a value, for every other paint program it has a higher value. Colors are too light too, to get dark colors i have to use extremely low values.

If i set the gamma correction to 0, palette colors look lighter than on the editor/image, and if i use the dropper i don't get the right color but a darker one, on the other hand RGB values are the same on other paint programs.

I'm on Vista, is it a bug or there's something i can do?

This is by design. The numerical values represent true intensity of the R, G, B channels. In RWPaint, for example a value of 40 represents an intensity in the middle of 30 and 50. This is not the case in other editors, because the sRGB and its gamma of 2.2 is not linear. All this complexity is hidden in RWPaint and a value of 50% actually means half-intensity. I would recommend to leave the gamma at 2.2, the setting may even disappear in new versions.

Do you actually need to copy the numerical value between editors? If yes, there is the hexadecimal code below and that follows the sRGB color profile.

Thanks for the answer but the more i think about it the more i'm sure there's a bug.
I don't care about numeric values and i love the gamma correction and the color range option, so please don't cut them!

I'm convinced that there's a bug because with different values of gamma correction both the dropper and the palette work with a 2.2 gamma correction value.
The palette alway shows the gamma 2.2 color version of the RGBA values and the dropper always consider colors with a 2.2 gamma correction value, in fact if the real gamma correction value is lower it returns darker color values, if the gamma correction value is higher it returns brighter color values, only with 2.2 it returns the right color.

In my opinion what shows color in the palette and what returns values in the dropper don't take into account the gamma correction value.

I don't use the 2.2 gamma correction value because i think its colors are too bright, look at this comparison, the same values of grey(from 0 to 250) but with different gamma values, first line is 2.2, second line 1.1, third line 0:

In a sense you are right, the behavior is inconsistent. In earlier version, the gamma value set in the configuration affected the whole editor. In the latest version, I have redesigned the color picker and decided to slowly move away from the configurable gamma towards "it just works, no settings needed" approach. Currently, some parts of the application honor the gamma value from the configuration, others don't. So, it is best to keep it at 2.2. (BTW 0 is an invalid value, 1 is used instead)

On your image, the last line looks correct and it actually has a gamma of 2.2. The first line looks like the gamma correction was applied twice. Perhaps, if you told me how you made that image, I'll be able to pinpoint the problem.

I am aware that I am making some scenarios more difficult or even impossible by removing the customizable gamma setting. For example, if someone wants to use RWPaint to create textures for a 3D game and they want the textures to use linear colors (gamma = 1) and apply the final gamma within the 3D engine, there will be problems, they won't see the right colors in the editor. Eventually, RWPaint will support HDR with 32-bit floating point colors and it will be possible to select gamma while saving to formats that allow that. But it will still show colors in sRGB color space while editing. Having a calibrated display is highly recommended, because it is good to see the colors as they are supposed to be.

I made that image in RWP, i made the first one with a 2.2 gamma correction value, the first color has 0,0,0 RGB values, the second 10,10,10, the third 20,20,20 etc up to 250,250,250.
Then i made the second line with the same RGBA values of the first line after setting a 1.1 value and then the third after setting a 0 value.

I saw that my video card control panel in the color optimization options has a default gamma value of 1, is this the problem?

That looks strange, I tried to do the same and I am getting the 3rd line while having gamma at 2.2 (since the color picker ignores it, it does not really matter). Maybe... are you using the last version - 2013.1 and selecting the colors by typing the values into the boxes next to the color wheel+triangle?

The setting in your graphic card should not affect the editor. You can check how your system is calibrated by for example looking at this image: http://www.otake.com.mx/Apuntes/ColorCalibration/GammaPatterns.phtml When looking from far enough, the black and white lines should become gray that has the same intensity as the really gray box with 2.2.
