Bug 484017

The Plasma sticky note applet used to use this dreadful harsh RGB-maxed yellow color as the background: https://i.stack.imgur.com/debL2.png

The color was changed to a vastly superior color that's similar to that of a real sticky note: https://blog.broulik.de/wp-content/uploads/2023/11/Screenshot_20231104_122120.png

Okular color for reference: https://cdn.kde.org/screenshots/okular/okular-annotation.png

I propose we move away from using this color on highlights and pop-up notes in Okular by default. The default color stops for a yellow sticky note set by Plasma appear to be #f7eabf, #f9eecd. Something in that range might be appropriate.

One potential option is to make the pop-up note background less intense than the highlighter color, since they essentially serve different purposes. We could go with the sticky note color for Okular's popup notes, and something a little brighter for the highlighter (but still less intense than what we have now).

VDG input would probably be helpful here.
