Most of the longest wavelengths (reds) of visible light are being reflected, compared to the other colors. The shorter wavelengths are mostly being absorbed.
Red light creates monochromatic color : all objects will appear in shades of red from brightest (white becomes bright red) to darkest (very dark colors appear dark red or black). So something green would not necessarily appear black, but a shade of red corresponding in hue to its grayscale equivalent.
Red is the color that can mostly be seen through anything like fog or smoke red is easiest to see through those gasses.
When you add methyl red to a solution it will indicate it's pH. When the pH is under 4.4 the solution will appear red in color (or maybe pink). When the solution is above pH 6.2 it will appear yellow in color. Any where in between will appear orange. So if you add base to a red/pink or orange solution it will turn yellow as the solution becomes more basic. But I honestly do not know th actual chemical reaction that causes the indictor's color change.
Purple will often appear brown or even black when it is very intense. If you have this problem in your paint mixing, try adding the color to white to obtain the color you wish. Red and blue still make purple, but the color needs to be lightened.
