Color feature request

rvijay · 02-04-2011, 01:12 AM

In the Calibre eReader it will be helpful to have a feature to change text color and background. By experience I find that a black background with a yellow text is best for my eyes, specially at night.

This feature is presently available on the iPod ereader.

Thank You.

You can change the custom css. Open the reader, go to Settings, and on the User Stylesheet tab put in something like:

body { color: #ffffff; background-color: #000000;}

That will give you white on black. Adjust the "color" style for the shade of yellow you prefer. #ffff00 is bright yellow, but you'll probably want something different. If you don't know the hex code of the yellow you like, try matching it in a paint program like Paint.NET. If your program doesn't automatically generate the hex value for you, you convert it easily enough if you have the RGB 0-255 values. Just convert to decimal (Windows' built-in calculator in Programmer mode can do this) and put then in as #RRGGBB. For example, the blue message headers here on mobileread are #6384B0, or 99 Red, 132 Green, and 176 Blue.
