The user @i-stubbed-my-toe said on @griffpatch “To me, the Looks and Motion blocks look the exact same color, so I think Scratch needs accessibility options for people who have deuteranopia.”


A lot of people find using the colors of blocks to distinguish what they are very helpful. But some users can't really tell the difference because they can't easily tell colors apart. An option to make blocks even more distinguishable or even to change colors to whatever you want for easier recognition would be very nice. I know a high contrast mode exists but that's more for making the text in blocks easier to read and doesn't help much in this case.

I think that the best option is allowing people to select their own colors, as a certain color scheme may work for some people but not for everyone. This will make scratch more accessible. We should have presets for different kinds of color blindness but a color selector would allow everyone to make a color scheme that works for them.

@SCLF-Xingshu also suggested in the replies to add images inside of the blocks like in paint blocks for easier recognition. This could be added along with color changes but shouldn't be added seperately because it takes more time to recognize images than colors.

If you have any suggestions of stuff I could add or remove tell me in the replies!

As a strong protan I support

Honestly agree, since the high contrast blocks didn't seem to help with colorblindness (which was one of the intended effects of the update and the purple update) really, as I showed with screenshots (I also made custom modes for each type of colorblindness somewhere)
Edit: Actually I didn't finish achromatopsia but yea

Note: Approximation, but yea
“Original” blocks (these are what the colors are called in the editor):
Deutan:

Protan:

Tritan

Achromatopsia:

And then the high contrast blocks:
Deutan:

Protan:

Tritan:

Achromatopsia:

Mockups I made for this too
Protan colors (I made 2 for this one)

Tritan

Deutan

(these were also intended for more severe colorblindness)

I can't see the images for some reason.

Are you on a school computer (try from home as the images are on cubeupload)

No. For some reason I just can't see them.

I'm able to view them, does your device/computer have any restrictions?

I don't really know lol. Wait a second. This is a school computer. That explains it. Not sure how I forgot that lol.

bump (not my post but needs more attention)

I've created a single colour scheme that should work both for people with protanopia and deuteranopia (I used simulators to check contrasts):

Modified colour scheme (Normal Vision):


Protanopia (Simulated by Brettel 1997):


Deuteranopia (Simulated by Brettel 1997):


I'll work on schemes for tritanopia and achromatopsia later, they'll just be more difficult because they're very different from protanopia and deuteranopia.

I'm wondering if extension block text may be too hard to see for protanopia, or if Control and Operators could be confused there, and if More Blocks and Lists could be confused in deuteranopia.

Though I think these should be presets, with custom colors allowed too.

Can you provide feedback on my block colors for protanopia?

My eyes are bad, so the Motion and Looks look very similar. Control and Variables looks similar to me, too. This is a good idea!

Your color scheme is quite good, but the extensions and operators blocks are very similar… also motion, sound, and sensing.
It's still better than the original scheme though

I can post a discussion forum now.
I like @shrimplink colors, they are very easy to tell apart for deuteranopia.

How about, instead of changing colors, do as the extensions blocks, adding a image describing the category of the block ?

This seems like a great idea!
