I've been noticing that color fidelity on the echo buttons sometimes surprises me. I understand that they're lights so it doesn't surprise me that darker colors (like navy) aren't all that true to form. Beyond that, I've found some colors that just don't show up well. For example, brown (#733a2f) shows up very close to pink (#e472bf). Through hunting and pecking, I'm finding good colors to use, but I'm wondering whether there's any guidance beyond this on what shows up well and what to stay away from. Thanks in advance!
