While posting an answer on UX.stack (then moved to Graphic Design) I found out I wasn't sure about how to express this:
The Go button size should be bigger and present the best contrast of all since it's the primary one.
1) Is present used correctly? Should I have used another verb instead?
2) Is best the correct adjective for contrast, or would highest be better?
3) Is there anything else to correct in the sentence?
