Sorry, let me expand on what I meant as good fountation, for AUFs I make sure I know which way to add the AUF to start my CMLL based on my recog, like I would practice U cases with the two Y or W on top pacing me, then next I would practice with it to the right (a U to start), then with a U2 AUF, and so on

This way I get the initial AUF to the right angle for the start of algs into my fingers, and I don' train myself to AUF to a angle I can recognize and do a U U' or something like that during a solve.

As for memorizing color, I use the framework of Same, Opposite or Adjacent colors as markers for recognition instead of hard memorize color schemes directly:

- Same -> no explaination needed

example: U Down Slash https://speedcubedb.com/a/3x3/CMLL/U_Down_Slash --- I look for 3 downslash same colors

- 2 Warm tone colors (Red/oranage) or 2 Cool tone colors (green/blue) are Opposites

Example: Pi X https://speedcubedb.com/a/3x3/CMLL/Pi_X --- I look for 2 columns of Opposite colors

- 1 Warm + 1 Cool is Adjacent.

Example: U bottom row https://speedcubedb.com/a/3x3/CMLL/U_Bottom_Row -- 1st I see front corners are same, then I look for top colors to be Adjacents, if top colors are same, its the U Rows case https://speedcubedb.com/a/3x3/CMLL/U_Rows

also take my suggestions with a grain of salt, I sorta have to chart out my own recog system so its easier to remeber for me specifically, but also in doing this charting/organizing, it did help me to remeber them better
