New Theme hard to see. We need a choice!

I did not believe the new theme for Zoho Writer was going to be forced upon us. For some reason I thought it would simply be an option. I checked it out, thought it was hard to see (grey on grey really?) and I went back to the other theme. So today I login and there is that horrible grey on grey theme with no way that I can see to change it. Come on... It's not easy to see. If people are working on documents for a long time and navigating around the application needs to be easy to see with no effort on the part of the eyes. We don't have much choice on Zoho about anything, at least let us have the choice on the theme. If you can't do that, then please stick to themes that provide adequate contrast.
