Guilty Crown 01 - 1920x1080

This could really use fixing. While it's a nice image to use, and the sakura petals look cool in the toolbar, it's too hard to read tab/bookmark text. You've got pink-on-pink for tabs, and orange-on-pink for bookmarks, both of which are way too close in shade. I would suggest trying out other text colors (white, blue shades, etc) instead. And perhaps blur the toolbar section, so the chunks of petals don't blend so much with the outlines of text and icons. At least you used separate text colors to distinguish which tab is active, so if you do revise this, do try to keep that feature with another color. Good luck, I hope this can be improved.

Cannot see the tabs that are not highlighted. Pink color fonts and sakura are not easy to distinguish.
