Yeah I saw some of those and when I cross referenced some online resources I couldn't get much on the Pali reverse to English. When I do this I get a better understanding on context and usage.
For example nīlalohita is basically saying blue-red in English, quite interesting. Pāṭala and puppavisesa can not be found. I think puppa might be alternately spelled puppHa, and I've found that, but no visesa.
So my next question is does anybody find English translations for these three words? And, does anybody have experience hearing or using this word (violet) in Pali?
