Have a shape. Using format shape, background, it shows all possible colors. When selecting a new color it either doesnt stick (for example choosing light green below results in gray) or selecting a light green in some it changes to a florescent green, not matching the color chosen in the picker.

Welcome to the world of Themes.
Open the shape's shapesheet and scroll down to the FillFormat section. Do the cells contain lines like
GUARD(THEME("FillColor2"))
or
THEMEGUARD(MSOTINT(THEME("LineColor"),80))
?
Thank you! Will investigate. Its quite obvious this is a complex and powerful app, probably being used by new people like me as if it were Microsoft Paint ;^)
