[EuiButtonGroup] Compressed selected button is hard to see

[monfera]

The background-color for .euiButtonGroup--compressed .euiButtonGroup__button--selected is set to a very light grey #e9edf3, while the equivalent non-compressed, eg. buttonSize="s" equivalent has a way more contrasty anthracite color #69707d. Is it possible to make the compressed version darker? It'd also need the color to be flipped to white.

Proposed is currently what the amsterdam theme has. I know that we'd originally gone lighter because the compressed usage almost always had high form density (usually within panels) and was distracting against the main content.

Thanks @snide I didn't know, looks crisp! If the baseline theme isn't deprecated and the user has it by default or can switch to it, maybe a contrasty yet lightweight "selected" frame can be added around the icon, though it has tradeoffs that may have caused a rejection of this already
