Newbie question about colors

[Sam_Stamport]

I’d like to have a colorful to do list. Something like Cool Memo & To Do Tasks Colourful Reminder Notes - Apps on Google Play except the ability to color the background of each field as well as all the other stuff.

I’ve done some research and cannot find an app or a Windows program like this.

Sometimes black text on a white background is too harsh on the eyes. Excel has very nice fill colors, for example.

Thanks!
