Good practice in 'the basics' - like the good old days when many of us didn't use candidate numbers. A kite in 4s finished it for me (r7 + c8), tho' there are no doubt lots of other colouring moves.
PS. will have a look at your grids later - seem interesting. |

| I took out a 6 from the 68 UR, then colored on 2, then finished it off with a W-Wing on 24. There's also a 24-28-48 XY-Wing with pincer coloring that looks like it will also complete it. |

A Type6 UR* in R46C18 takes out <2> in R2C2, either R6C1=4 or R4C8=2 to avoid the [68] DP
R6C1=|4| => R8C1=|8| => R9C2=|2|(a)
R4C8={2} => R2C9={2}(b)
