improve priority color +2 and +1 because they look very similar

[mirthless29]

The RED color of priority +2 and the ORANGE color of priority +1 are very similar.

I propose a GREEN or YELLOW color for +1

As a workaround you can set your own colours using Custom CSS extension. Use like this:

:root {
 --color-priority-high:   #800000;
 --color-priority-urgent: #ff2222;
}
