#52 looks really good. I suggest to try the following
1. Try solid color of #52 same look/feel but solid not dark and not so light something in middle.
2. some quick variations where we use either tick mark or underline red (one of them not both) different ideas/fonts maybe to try.
3. Some other way of displaying the tick mark.
4. Try some ideas with 4 and remove the tick mark.
2. If you don't mind please give me #52 in blue/green color combination shading and solid
