I've never used the forums, so I don't know if I'm doing this right.
I'm finding it much harder since an update or two ago to see sketch entities. The purple color of projected geometry has become very dull and becomes almost invisible unless you hide whatever body you projected the geometry from.
The light blue color of undefined sketches also can be difficult to see. When you create a closed loop it now fills the loop with a translucent color. This further reduces the ability to see what color different sketch entities are. If you hit "shift-N" to colorize your different parts, most colors make it even harder to see sketch entities.
I feel like the only testing they did with these new sketch colors was in a blank canvas with no bodies, because that's the only place it looks good.
Worse yet, when you hover one of these closed loops, or a face or body (unless you turn on a bunch of selection filters), the part flashes to near white and all of the sketch lines become black. So whenever you are trying to add geometry to a face of a part that already has some geometry, you end up looking at a strobe light as you hover across to click hole in the part. But I've just dealt with that aspect for years.
