Mod that colours HitObjects based on the musical division they are on, now in osu!catch

For now bananas are not coloured by the mod and keep their yellow colour, since I think its better for the sake of readabilty (also it just looks kinda ugly?). Do leave your thoughts on that.

Droplets are always coloured to LightGreen, setting their colour to closest timeline ticks is wrong and looks incorrect since droplets aren't generated with them in mind.

I think you are going to want to exclude juice stream droplets from this as well because it is not guaranteed they are musically quantised to beats. See relevant wiki article.

Even looks busted on a few maps I checked as well:

it does look bugged, but do I just not change their colours at all or change it to the colour of the starting fruit?

[bdach]

Good question! Your choice. I sincerely don't know.

If you held me hostage I'd probably say to choose a single constant colour and colour all droplets with the same colour. Maybe the green there or something. But that's, like, my opinion.

I decided to colour them to Aqua

• 1/4s use aqua so I think it fits.
• I just like aqua a lot.

same

Uhhh reusing the colour of 1/4 for objects that may not be snapped to 1/4 at all was one of the things I would not have done... That seems actively misleading in a mod that's intended to simplify rhythm reading.

[Tenexxt]

I guess that does make sense...
Green it is then? (any specific shade?)

[Shavixinio]

If green doesn't appear on any other snapping then imo it should be fine. I've tested a few colors and I think Color4.LightGreen is the most readable, especially for people who play with background dim on 100%

should be LightGreen now
