Soaprman's idea:
All ranked mods and their possible qualities they add to the image:EASY - green hue
NOFAIL - cross picture behind/above
HALFTIME - hourglass behind/above
HARDROCK - red hue
SUDDENDEATH - bomb behind/above
PERFECT - crosshair ontop
DOUBLETIME - multiple images with increasing transparency (calculated with osu!) or just 2x picture above
NIGHTCORE - some anime image behind the letter. maybe Pippi
FLASHLIGHT - dark layer ontop
optional SPUNOUT - spinner picture behind
HIDDEN - uses "ranking-letter-HD.png" picture instead
Some examplesHD
HR
HD+HR
How it looks in-game
HR+HD and HR scores:
HD score and S no-mod
I am not very cool at colouring so excuse me, but you get the idea
Also I haven't tried adding images below ranking letters because I suck at gimp, maybe someone will do that for me :<
But the most extreme combination I can think of is HR+HD+NC+PF+SO+FL
It is done with:
HR red hue
HD ranking-letter-HD.png
images below: NC pippy
images above: PF crosshair, SO spinner, FL dark area
And I don't think it will look too cluttered~
UPD: Oh it also works for all other letters: SS, A, B, C, D
