Summary0016631: Multiple adding of a defined colour adds different colours
DescriptionDefining and attaching a colour seems not to use ONE consistent colour for different objects in one document.
Steps To Reproduce- Define a colour, e. g. RGB 111 in the attached test file
- Stick the colour to an object
- Pick the colour with the colour picker ("eye dropper")
- Compare the defined and the picked colour. You will see differences even without switching colour management on or off
- Explore even additional colours with switching colour management on or off

Color picker can only get what the window system delivers in its buffers. That means when color management in on, the color picker will get RGB values already adjusted for the screen. Scribus objects are never looked at when using color picker.

Also be aware that the human visual system has pretty different behavior when looking at a small patch of color or a large area of same color. Hence a small patch and a large patch may look different even if input color is the same.

Also in this document, "Simulate Printer on screen" color management option is enabled, so RGB color values have to go a RGB (color) => CMYK (printer) => RGB (screeen) route. There is pretty much no chance that the color picker can get the original RGB color values in these conditions.

Btw, there is the "copy properties" tool just left eye dropper tool which can directly copy item properties including named colors.

But both viewing conditions (colour management and printer simulation) may not change the real colour that is once defined and put into the document, in my understanding. But this seems to be so.
And it should make no difference to use a defined colour if color management is just on or off. It is a completely different thing than using a colour.

As previously mentioned the color picker pick the RGB values displayed by screen. It is incorrect to believe that color picker will pick values from any Scribus named color.
