Looking for feedback - a light transparent theme experiment

Currently, as a part of experiment, I'm working on light transparent theme for the website.

This basically would be the light theme with ability to set background image (inheriting some display adjustments made for "Picture", so dark transparent theme). Here is an early preview:

So the questions I have are:

• Do you like it as a new customization option?
• Will you use it?

For more a bit more details and to follow development you can check:

I like the idea, even if I will never use it. Bright interfaces make my eyes hurt. But I've always asked myself why the transparent theme is always a dark theme, especially since you can specify any image as the background.

Haven't looked at the implementation yet, but I hope things are composable. Not a theme with background and colors, but a separate background, separate colors, separate dark/light behavior.

Few more screenshots with a different image backgrounds.
