I moved the pink entry to a later position in the color table. Linkage should now have pink links only after there are more than 15 or 20 links in the mechanism. I started to notice that all of the images that I was posting were a bit pink looking and it seems just a little odd. No offense to anyone who is pink.
But if someone likes the pink links and the overall shade of the example mechanisms, let me know and I’ll build a special version of the Linkage program just for you!
