Color selection UI should not "disappear" if selected color matches the UI background color

[A--]

When selecting a color in a window, e.g. Fill color for Text Frame, the color is shown in a rectangle. To change that color one has to click that rectangle again. Now, if the user picks a fill color that matches the background color of the Text Frame window, then that rectangle "disappears" from view. The word "Fill:" remains but there's no visual feedback where to click to make a change.

Having a UI element "disappear" because of what color value the user has picked is clearly a bug.

Possible fix includes always using a contrasting border, or adding one whenever the color to she shown matches the background color of the command window. The former is probably easier to implement.

This issue seems generic to almost all color selection UI. For example in the Character window, the outline color is shown at the end, after the stroke thickness. Unlike the example from the Text Frame, there is no cue whatsoever that there is a color selection field, if the color selected matches the currently active background color for the UI.

Rather annoying isn't it?

I was going to suggest that translucent colours should have a chequerboard background to make them clearly visible against the dark grey; obviously translucent rather than a visually similar opaque colour; and far more representative of the selected values. Or at least make the contextual toolbar and the colour palette consistent when using translucent values.

However, as it is closely related to your view, perhaps the developers will take just as much (or as little?) heed of it here.

I had the issue with a light gray against a light gray background. Because that's how I prefer the UI. But yes. For something like showing the status of a color selection, the UI needs to give accurate feedback. It clearly can be done when you erase the background layer with a checkerboard indication.

The issue is not limited to lack of contrast between the location of the color swatch and the surrounding background, nor lack of feedback on transparency, but extends to the styles panel, where the names of the styles are formatted in their respective styles.

There are some styles that equally "disappear", for example if you set the font color to the UI background color.
