What is the difference between these two blocks? The first one works with a variable and the second one doesn't:

I believe the second gives you a color picker like the one in the art editor, but the first one only accepts numbers.

The one with the dropdown refers to the hue of the color, and so it does work with variables.

The second refers to a hex color code, so you can choose a specific color. It does work with variables, actually, if the variable is something like #3580C0, then you get a color like this.

Thanks for the replies. I think they might have come up with something a bit less confusing - I was struggling to help a child debug code where the second block had been used instead of the first by mistake. That mistake is far too easy to make.
