The darker green looks great, you could even play around with the fonts and make it thicker, larger, etc. I love Tink too Also, my husband (Jeff) and I will be discussing the posts and we refer to you a B-Kitty. lol
Okay, how is this green? I was trying for a tinkerbell green, cuz it's my favorite color and it is to light.
The contrast against the default white background it what makes it hard to see. You CAN change the background color of your posts in your profile. Try it out and see how you like it. You can always change it back, right!
