http://rocaca.com/manga/the_palette_of_12_secret_colors/I had an urge at 1am to read the whole 6 volumes
Overall: 9- Cause I gave my sleep just to search for this manga online...cause the library has to be closed at 1 in the morning...

Read it! This manga is so..underrated because it is not on any major manga sites..is just sad...thus provided the link. ^^
