colour blindness

[Anonymous]

About 10% of men, like myself, have varying degrees of colour blindness. As a consequence, we may not even notice a snap shape appear against a background colour that can simply soak up the colour of the snap shape.

Consequently, it is important that we are able to adjust colours of backgrounds, snaps, entities and so on to deliver suitable contrast for recognition.

Tonight I downloaded the latest version and began playing by drawing a circle, and then trying to draw another circle in its centre. Believe me , with the default settingsas they were, I could not see the "centre" osnap shape unless I brought the screen right up close to my face.

Some months ago I wondered why the object snap facility didn't exist. Now I think it was simply because I couldn't see it. This may be something you 20-20 vision people haven't thought much about.

I don't think we have given this the attention it deserves.  I have created a backlog item (FUS-15255) for us to review and improve UI elements with color blind awareness in mind.  If you have any other specific issues that are causing problems please point them out.  I know there are some tools available to simulate color blind display.  

Thanks

This would be a huge improvement.

One thing I'll ask you to consider: I have a very hard time choosing custom colors to assign to make a usable palette when given that option. I know that would help many, but others like myself would benefit most from being able to choose from a few different pre-defined sets that are likely to work for different types of color blind users. Thank you!

Component color cycling, super awful choice of colors. I found another, again I only knew that colors were different because the person making the screen cast clicked on each and talked about how useful it is that some are green and some are orange. I'm actually pretty surprised at how many cases this comes up in the program. I strongly suspect that the person designing the color choices wanted to have the colors all go together in terms of depth or shade or hue, though I don't know which of those is the right term here. In reality you want exactly the opposite! You should be able to instantly tell the difference with the screen in grey scale. Other cues like hatching or dots is good. A pretty interface that is useless no good. An ugly one that works isn't ideal, but is a lot better. The example
