[1] was a similar idea where color is determined by the prefix, so for example `currentIndex` and `randomIndex` are distinguished from each other but `currentIndex` and `currentIdx` are not. I'm not sure about both because, i) there are only a handful number of mutually distinguishable colors ([1] does mention the same complication), ii) we often want to highlight both the similarity and difference among identifiers and the cutoff is not clear. For i) we may want to leverage more formattings; for ii) I really don't have a good solution.
