The best advice is from Feliks' blog:
You can train your LL on different colors than what you're used to help make parts of the CN solves more familiar. In practice, the only real way is to just do lots of solves on the other colors and suck it up that you're gonna be slower for a while. I used to let the first 6 days of the week each be for solving only on one color (like Monday = Red Cross, Tuesday = orange cross , etc) then let the 7th day be for combining all of them and trying to do what cross seemed best for each scramble.
A similar thing happened to me. I started out color neutral, but then I came across one of J perm's older videos and in it he said something along the lines of knowing the color scheme helps and I miss interpreted that as if you don't know the color scheme then you aren't color neutral. So I switched to dual color neutral because of that and I tried to become color neutral and everything went well except for the fact that I didn't know the color scheme for other crosses, so I spent 3 months trying to learn the color scheme for crosses until I figured out that it wasn't really that important.
i have LL recognition by pattern regardless of color
In that case you should do f2l-only solves on whatever color you are deciding to practice. Make sure you remind yourself of what you need to look for and what you don't need to look for before starting, as often times people will pause for a second to realize what cross color they are doing. This becomes natural eventually, however you should do this at the start as it will tremendously help you improve. Sometimes this happens to color neutral solvers when thought they did a different cross color, and then when they look for pieces they thought they needed, they can't find anything, and when they switch what cross color they thought they were solving on to what cross color they had to solve on it would take a second for them to filter out the right colors as the color patterns have changed, just like how someone earlier pointed out. Also, make sure you can plan your cross and cross+1 if you are at the level where you can do that.
that doesn’t mean you’ll be used to how it looks. You’ll still need to practice to get recognition to the same speed
i Stated earlier that i have tried to be color neutral. the only problem ive come across is F2L cases
Haha i havn`t, i can do ll easily.
as far as color neutral goes, if i see a better cross in a scramble i want to be able to execute the F2L to match the good cross
