it could help to write more about the context, the task, or show your code....
(I see it in the other thread now)

when you have a painting program you have a fill functionality so you can use a variable to store the color.

to do so use

1. color fillColor = color (222,2,225);

so every time you fill, you use the color to fill

1. fill(fillColor);

with another function you can change the var. E.g. with a color selector.

that's about it.

(remark: when you track the fill color in the sense of a history you could have a back button to go back to a previous used color.
then you would use an

1. array color[] historyFillColor = color [1000];

or so. but that's probably not what's asked for...)
