Zebra colouring

  1. What browsers show this problem? I'm using Google Chrome, but I think it happens on every browser.
  2. Please share an example project (if possible).

  3. Describes the steps to reproduce this issue. Make a custom block with only a C-shaped input.
  4. What does Snap! currently do? The zebra colouring goes all weird.
  5. What should Snap! do instead? Fix the zebra colouring.

Yup, confirmed. Thanks for the report.

Happens on Firefox too. Happens when you change the color of a block; it doesn't change completely.
This is changing from Operators to Looks. Putting something in the slot or taking something out fixes it.
