Hi.
Please can someone answer this question?
I’m talking about the beta GitHub integration.
If it’s needed, my project repository is below.

How do you change the colour of custom blocks and categories?

Add a “color” value (as CSS color) on the namespace comment:
```auto
//% color=#ff0f0f
namespace mycode {
...
```

We’ve noticed that color keywords with the correct color really helps the “natural language” -\> “code” translation.
