PR Summary
Fixes #17243
The problem was that
mcolors.to_rgba_array(c)can raise two categories of ValueErrors. One are generic array conversion-related errors, the other is our ownValueError('RGBA values should be within 0-1 range'). Only the former should be catched and rewritten. Our ownValueErrorshould directly surface.I chose the simple approach of just checking the error message. One could alternatively introduce an own Exception subtype. But we're not really doing that in other places and
ValueErrorseems exactly right for out-of-bounds numbers.
