highlight color for text selected for next replacement has contrast too low
In a file with a large amount of text visible in the window, when doing a find-and-replace for one character (like a single quotation mark), and the function selects the next small string in the file for potential replacement, the highlight color (tan or light gray, I think) makes it hard to see. I found it faster to do one find at a time, replace manually, and repeat for each instance. Please choose a higher contrast color. (This will also improve accessibility.)
This was in gedit 3.18.3 on an up-to-date Ubuntu Linux platform. I do not know what libraries are in use; I assume they're the defaults for the installation.
Possibly relevant is bug 748662, about gnote. This issue is about a light color on a white background, whereas that issue was about a dark color with dark text. Both are low-contrast problems, but opposite problems.
Possibly relevant is bug 669505, but that's about bluefish.
Possibly relevant is bug 726272, about vte.
