Frankly--it just resembles a plain black heading, not near enuf contrast between the three colors. Just as soon have simply BLACK, which think shall do!!!

Great use of colors also the red bar over each tab makes it so easy for me to see which tab I am on since I like to open a few. I'm not overwhelmed with a lot of colors. I hope you make more like this. A color over each tab makes it easy on the eyes to flip from on to the other without closing the wrong one.
