RandyN,
What you could do is create a 'circuit color reference chart' drawing that would have your commonly used colors in a small text-sized filled box. Also include the column/row of that color, as shown in the color selection window so that the same color/shade is always used. Then give it a 'typical usage name' such as, "Main Power", "12v", "5v", "GND/Common", etc.
Print that reference chart and keep it handy so that all of your drawings will basically be 'standardized'. As you add other circuit color definitions, you only need to add those to the chart drawing and print the revised chart.
Eventually, I expect, you'll begin to memorize which color is typically used for what without always having to reference your chart.
Also, a good habit to get into, would be to include a similar 'reference chart' within your circuit drawings, as there can be a very noticeable difference between printed and on-screen color shades.
Green is a good example of that since Green is a 'true color' on a monitor, but is a mix of blue/yellow and possibly a smidgen of other colors, depending on your printer's interpretation of "true green", when printed.
-- That's also why I suggest including the column/row of a color on your chart.
If possible, please submit some of your circuit drawings for posting. We haven't had any new shared drawings for quite awhile. If you have a collection of schematic symbols, not already included in DeltaCad, please submit those for posting too.
Thanks for posting your questions & requests and giving us 'something to do'.
