I have not time to research this myself but google turns up many comments I have not looked into these but I am sure others have had the same issues, here is a search result:

Have had a quick browse and there seems to be a consensus about yellow being caused by chloride ions.

Highly appreciate your assistance

H₂O + NaCl + Al + Unknowns In Al source + Unknowns in H₂O source + Unknowns in NaCl source 9V electrolysis   Result?

So the above reaction is what we are discussing.
I am just posting this for informational purposes.

I do not know why you are not buying your NaOH from someone like

Because i have a house, like 10mins walk to the beach. So I think I have all the minerals to produce my own chemical

Nobody here seemed to realize that you will not get a pure solution of sodium hydroxide from electrolyzing salt water, even with pure sodium chloride, pure platinum electrodes, and pure water. You need a special kind of electrolytic cell for sodium hydroxide. Without it, the remaining solution will be heavily contaminated with sodium oxychlorides, the main contaminant being sodium hypochlorite, or bleach. It's yellow.
