need help adjusting the color on my monitor. every was fine for the most part but i thought the red could be turned up a little. and since this is my first arcade monitor, i have totally screwed all the colors. yes i am a retard and i didnt mark the settings.

so basically the picture is dull. biggest problem i see is that anywhere is supposed to be red is black. i have searched around and found a few basic guides for setting up colors but i still cant get nothing.
i am pretty sure the monitor is a Electrohome GO7. looks similar from the monitor ID page. Attached is a picture to make sure.
I have two drives, red and green. and three cutoffs, red,blue, and green obviously.
