3. Text: #878787 or #3498DB (popular in our main icons)
4. Enter Event: border: 2px dashed #1D76D5; background: #91C7F9; color: #1665C0;
(The default ‘blue’ for the frame clashes with the interface.
Here, the frame, background and text use the same colours as the icons, so it looks as though it’s part of the main UI.)

Thanks! I will give those a try.
