color profiles and color space

[Aira]

ive just noticed that the color information in sai changes when i save them in and some image format
but i want to retain the exact original colors i used
ive been tinkering with photoshop colorprofile tools to try to detect what color profile sai uses ;A;
anyway i think it is quite hopeless

the point is...
what color profile do you use?
apple rgb, colormatch rgb and srgb seem to lose saturation making my images lose bright colors and become grays
adobe rgb seems fine
i tested wide gamut rgb and seems to be closest to what sai uses although probably a little brighter

edit:
hmm its kinda pointless
it seems that whatever color profile i select, it all appears the same when i upload them and view in the web browser ouo
