Translucent white over the cool-dark sidebar reads as muddy grey;
that's the same root cause as the earlier #1d1d1b warm-grey complaint.
Any unsaturated tint loses against the dark sidebar bg.
Switching the home tile to accent-lavender (RGB 196,181,253 — the
endpoint of the mark's gradient) breaks the grey because saturation
defeats the grey-on-grey muddiness. Lavender also (a) complements
the gradient mark sitting on top, (b) parallels Discord's brand-
coloured home button pattern, and (c) gives the sidebar a clear
semantic colour hierarchy: action = mint, home = lavender (brand),
spaces = user-defined.
Three states escalate by alpha (0.08 / 0.16 / 0.28) so corner-morph
and fill-brightness both signal interaction.
