Color value difference between Rhino and Grasshopper


I found that Color Picker in Rhino and in Grasshopper are slightly different.
The satuation value ranges from 1 to 255 in Rhino while it ranges from 1 to 100 in Grasshopper Color Swatch component.

I was not aware of this problem since today, but today I needed to choose exactly same color as used in Grasshopper, and I ended up doing a quick math, which is a little pain.
