What are the 200 pen colors?
When I choose "help" on the
change pen color by ()block, it says there are 200 defined pen colors.
Can you give me the rgb values for these 200 pen colors?
The reason I would like this is that I'm creating a Greenfoot library that simulates as many of the Scratch blocks as possible, as a way to help Scratchers in my computing clubs to transition to Greenfoot. If I'm going to implement a method changePenColorBy(), I need to have built in the 200 defined colors in Scratch.
Thanks much. Hope to hear from you soon.

Re: What are the 200 pen colors?
So, they are computed? So, how can I compute them? What is the algorithm? If (255, 0, 0)
(red) is the first color, then what is the next rgb value?
Thanks.

in scratch it works with HSB, not RGB...
the pen color is hue, brightness is brightness 
try to find a way to convert

It's in HSL format, and the hue is calculated like this:
((Input) * ((360) / (200)))
