Hello Tig (and Chris),
Thank you to you both for the original colr by slope ruby and the modifications to it to show colors for various slope angles. I have found the rz. file but it is unclear what needs to be edited and replaced. Is a new color by slope plug in for the various angles available?
Thanks again,

Make a backup copy of the original ruby script outside of the Plugins folder so it won't try load twice. If you mess up then you have the original to use again...
Now edit/replace the version that's still in the Plugins folder, as set out above [open with Notepad.exe or equivalent plain-text editor].
Save it and restart Sketchup - all slopes should now be colored in the angle-ranges and colors you've specified...
