Description

Disabled blocks have low contrast and can be difficult to read. This screenshot contains a few random blocks here only illustration purposes:

Image

We have been preparing inclusive projects for students with visual impairments. In these resources the students start with a project with all required blocks present in the workspace and they need to assemble them the right order. In this arrangement, it can be quite difficult for students to identify/read the blocks with this contrast level.

MakeCode version:
makecode.microbit.org version: 8.0.21
Microsoft MakeCode version: 12.0.18
microbit runtime version: v2.2.0-rc6
codal-microbit-v2 runtime version: v0.3.2

Research direction

Start by reproducing the contrast problem in the MakeCode micro:bit workspace using the screenshot and issue description. Trace the styling or rendering path for disabled blocks and compare the result against an accessible contrast target. Done means disabled blocks are easier to identify and read without changing the intended workspace behavior.
