Colorblind accessibility for blocks
Scratch block colors are very hard for colorblind people to tell apart.
I'm colorblind (deuteranopia) and the Motion and Looks blocks are the same color, Sound and Sensing are also the same, Operators and My Blocks and Extensions are all the same, and finally Events and Variables are the same.
I think Scratch should add colorblind options in the block mode drop-down, one for each type of colorblindess, or just let users choose their own colors (This was a feature in Scratch 2.0)
The high-contrast mode wasn't made for colorblind people, it was made for people with bad eyesight who might not be able to clearly see the blocks, so please don't reply saying that the high-contrast mode exists.
Here's a simulated picture (not completely accurate) of how I see Scratch blocks:

I suggested the one for each type of colorblindness, let me find the post with all the screenshots.
Also, I remember the Scratch Team stating that the high contrast blocks were also for colorblindness, as well as the purple.
Edit:
Simulation for what it looks like currently:

Your colorblind?
This is good, but make the colors fit scratch's fun vibe.

No, it's a simulation of what they look like for that user. This is good, but make the colors fit scratch's fun vibe.

Maybe for tritanopia, we could use something close to the 2.0 colors? I just tested vanilla 2.0 blocks with tritan, and it seemed mostly or completely fine (with multiple different simulation methods).

The black one (with “slider” in the dropdown) is an extension
Symbols could also be used
