Adjust Color Contrast , instantly, Online

Red/Green/Blue (RGB) are additive primary colors , used to create colors on digital screens by combining these lights. It is the standard color system for digital screens (monitors, televisions, digital cameras, and scanners) producing white when all colors are at full intensity. CMY stands for Cyan, Magenta, and Yellow, a subtractive color model (subtracting light) used in color printing, where mixing all three produces black (dark tones). This online system helps you to produce a more vibrant, colorful picture, and also helps you customize the picture through easily adjustable color curves. To increase or decrease `color contrast`, you should adjust the curve to a smooth shape. If you set the left part of the curve below the x-axis, the corresponding y-values will be minus, and thus the light of dark colors will be further reduced. vise-versa, to increase light colors, and bright colors (colors with more light) keep the right part of the curve above the x-axis, for plus values, which will increase light for light and high color pixels. Also note that, if you increase lightness for low light areas (left part of curve), it will produce a rather dull or low-contrast picture. And similarly, if you reduce light of high color areas ( right side of curve) , this also could produce a rather , low contrast , less atractive picture. There fore, these adjustments must be done with gradual change and test.

Try to make the curve as smooth as possible ( less sharp) , to make sure the color transitions are smooth (gradual), and realistic. You can also adjust the `intensity` value, to increase or decrease the effect.
