constify newColor?
Also, you could cast oldColor.size() in C++ manner, e.g. static_cast<size_t>(...)?

X11 uses 16 bit values even for 24 bit screens, because the actual values that are sent to the DAC can have higher precision than the screen pixmap. I doubt that Wayland has reduced the precision, so I don't think checking values here is right.

I forget to remove this comment. This is not an issue since we can "stretch" the image over the whole uint16_t value domain linearly such that image 1 is associated with the largest uint16_t value. By that we have well defined arguments in any case.

The array size though is checked before that in the checkArg call by comparing it with the size set first by the compositor.
