topic iconWrong colors

Hi,

i forgot when I updated to the newest version of RW Paint, but after the update, colors are wrong even if the hex-code is directly inserted.

Example:
Start with a new empty raster image
Select Fill tool and enter 202020 as color
Fill
Now the whole area has color 1A1A1A instead of 202020.

This gets worse the darker the color is. Everything below a certain threshold just results in black.

Am I doing something wrong or is this a bug?

You can check what version you have in the main menu Help->About RealWorld Paint

It could be that at certain times, there were problems with colors due to handling of sRGB. But it should be OK in the latest version. If not, please update the description - for example what method do you use to check out the actual color? Do you have only a single layer or more, do you have any layer styles applied to it?

Hi,
I'm probably not the best with words, so I made a gif: https://imgur.com/a/FJOqUxB

Its really cool to get such a fast reply. Its 2:00 midnight in Germany and somehow I thought the whole world is currently asleep 😊

Edit: Ah, I forgot to mention:
- No layer style
- Blending mode == Normal
- My Screen (Hardware) uses default RGB888 (no 10bit or HDR). Maybe that matters
- Windows 11 (10.0.26100)

OK, thanks for the video, you have actually found a bug in the Dropper tool. It was not properly updated and reports wrong colors, the pixels in your image are in fact correct.

I will fix it, but for now, there are workarounds. Many of the drawing tools (including the Flood fill) can act as a dropper tool when you hold CTRL key and click a pixel. This method should work fine and give you back the right color. This is what I use and that is the reason I forgot to update the dropper tool. Also, the small dropper button in the color selection box should work, but this one works slightly differently - it actually takes the color from the Windows screen (so, no alpha channel), while the Dropper tool and CTRL+normal tool take the color from the raw pixels of the raster layer.

The problem was caused by an update, older version of RWPaint approximated the sRGB color space with a 2.2 power curve and the new version user proper sRGB mapping. The difference in those 2 methods is what caused the discrepancy.

(and I was actually feeding a baby, so I was awake at that time)
