Me too. For me, the yellow is impossible to read, bold or not. I never thought of highlighting, though! The "sandy brown" and teh cyan are also too faint for me.

I admit I used yellow in the "Dog Humor" post, but it was only on the "butternut squash." I couldn't help myself, I was having such fun!
Mostly I stay away from the yellow and pink.

I like the blue, royal blue and red; but I always put them in bold. They seem too fine otherwise.
