[Q] recamendations on theme or apps topic

i used the cf auto root and NH7 so still 4.4.4

im looking for some suggestions from the experienced users of either app or themes based on my needs.

im vision impaired and deaf so sound is whatever but vibrations are great if customized. as for vision, i work best with the dark themes. mainly like everything is a black nackground with light colored text. even google chrome. i can do it on my pc but not phone and i did try firefox but altho it worked, not very stable to use. i do tend to lean towards go launcher bc of editing how i like and still simple icons. nothing fancy or whatnot. but another app would be like a note pad where background is black, font is white but you can change the size of the font. ive tried blackbook app but its perfect if i could just change the font size. can anyone suggest any dark themes or apps that could benefit me? im not to ready to update to lollipop yet but if its the only way to get certain things i need, i will but for now i would like to try to stick with android 4.4.4. thank you in advance to any help and advice!
