Once they are implemented soon:
96th: Dark green
128th: Dark red
192nd: Dark teal or blue
384th: Gray (same as the 192nd color that is being used now)

No need to make them now, only after they get implemented.

Sexy-editor: Note colored mines (meant to be used as an editor noteskin, but still playable in the actual game)
Sexy-flat: Turns all notes a single color
Sexy-original: Brings back original techno column colors (top diagonals red, bottom diagonals blue, left and right green, up and down yellow, center pink)
Sexy-solo: Uses a solo color scheme (4ths orange, 8ths blue, triplets pink, other notes purple)

In 5.0, these are separate noteskins. In 5.1, this can be put into one noteskin, and changed in noteskin params (ask hanubeki for help on implementing noteskin params)

Make this image completely transparent to erase the edges on the mines.

Minefields are mine holds. They may or may not get implemented in a future 5.0/5.1 build.
Can graphics be made for them, in case they get implemented later? Only the mine head has to be animated, not the minefield body or bottomcap.
What a minefield is: Basically a mine hold, do not step on the panel the minefield is scrolling on until the minefield has passed. They are not implemented yet, but may get implemented after opinions from some people.

It also needs some lua editing which i'm not that good at.

Diagonals should use _hflash _downleft 8x8 (doubleres)
Center should use _hflash _center 8x8 (doubleres)

The diagonal arrows has only 12 frames animation instead of 18 of the normal arrows. Needs fixing in lua. It should be easy for those who know lua.

I'd like to use the Down Tap Explosion Dim Boo 8x8 (doubleres) image for the perfect timings. Could someone please help? :)

Just tested it. It doesn't work right in pump and techno mode, on the diagonal arrows (they flash in a different color and the center one keeps cycling through the colors)

I think I know why. The frames of every direction have to be 18.

All those "burger" and "key" and "para whatever" notes can be removed, since this only works on techno. And edit the lua file, to remove all these notes that aren't needed. Same thing with the "hand whatever" and "leftfist", "leftfoot", etc. Remove everything except left/right, up/down, the diagonals, and center. It would look weird to use this noteskin on other gametypes.
And for the center, can it be pink/purple like the original technomotion game? I can use paint.net to re-hue it. A center receptor still needs to be worked on.

I'd like to see a rhythm colored version of this, with blue holds/gray rolls (5.0) and note colored holds/rolls (5.1). I will re-hue the images according to this:
4th - Blue
8th - Red
12th - Pink
16th - Yellow
24th - Purple
32nd - Teal
48th - Orange
64th - Green
192nd - Gray
