Additive vs Subtractive Colors – Difference and Comparison

What is Additive Color?

Red, green, and blue are additive colors, known as RGB. The additive color model explains how light interacts with the human eye to create all of the visible spectrum’s hues. Furthermore, additive color creates a visible range of colors, starting with black and adding red, green, and blue light.

The outcome becomes lighter as additional color is added. White light is created when all three colors are blended equally. These contraptions’ shading-delivering techniques are straightforwardly founded on our aversions to red, green, and blue light upgrades. Similar to the natural eye, these gadgets should investigate a lot of shading information on the screen.

These gadgets reasonably reflect the eye’s reaction to the added substance primaries to make a bright deception. For instance, every one of the little pixels of a PC show joins unmistakable forces of red, green, and blue light. Since these pixels are so little and firmly pressed, the RGB reaction of the eye is deluded into recognizing various tones when there are just three.

What is Subtractive Color? 

Cyan, Magenta, and Yellow, or CMY, are subtractive hues. The subtractive color model begins with white and ends with black in the additive vs subtractive color comparison. So, what exactly does this imply? The resulting hue darkens as you add more color. As a result, when you print C, M, and Y, on paper, they absorb light, leaving your eyes with no reflected light and seeing darkness.

Printers, for instance, should communicate with mirrored light to make tones on paper and different substrates. The subtractive primaries cyan, fuchsia, and yellow are utilized in resistance to accomplish this. In the noticeable range, cyan is something contrary to red, maroon is contrary to green, and yellow is contrary to blue.

When cyan, red, and yellow colors are put to a white, reflecting substrate, they assimilate or eliminate their contrary partners from the white light. Printing methods utilize cyan, maroon, and yellow inks to control how much red, green, and blue light pondered white paper.

Difference Between Additive and Subtractive Color

  1. Added substance shading blending is brought about by the synchronous impact of many shading sensations known as aggravations on the retina. Contrary to additive color mixing, subtractive (multiplicative) color mixing does not include the mixing of color irritants, but rather the subtraction of color.
  2. When three light zones are optically combined, additive color synthesis occurs (red, green, and blue). Subtractive color is achieved by combining the primary hues of the materials (cyan, magenta, and yellow).
  3. Added substance tones incorporate green + red = yellow, blue + red = red, and blue + green = cyan. Subtractive blending is shown with yellow + red = red, yellow + cyan = green, and fuchsia + cyan = blue.
  4. Additive color prints are opaque to the eyes, implying that one color over another does not allow it to be seen. Still, subtractive color prints are transparent to the eyes, implying that one color over another does not allow it to vanish.
  5. Subtractive color uses the CMYK system and follows the RGB system, which displays primary colors with varying light intensities. On the other hand, additive color follows the RGB system, which displays primary colors with varying light intensities.

Comparison Between Additive and Subtractive Color

Parameters of ComparisonAdditive ColorSubtractive Color
TerminologyAdded substance shading alludes to a circumstance wherein shading is framed by consolidating apparent light from a few hued light sources.Subtractive color or subtractive color mixing predicts the spectral power distribution of light as it passes through successive layers of partially absorbing material.
BasisIndividual wavelengths are added or subtracted in additive color.Subtractive color is based on the absorption or removal of specific wavelengths from white light.
UsageKeep the color mode RGB if the final product is only seen on a screen or monitor.Remember to adjust the color mode from RGB to CMYK if the final result will be printed. 
Color CombinationRed, green, and blue, or RGB, are additive colors. Cyan, yellow, magenta, and black (known as CMYK) are subtractive colors.
Starting PointTo create the visible spectrum of colors, the additive color starts with black and adds red, green, and blue light. Subtractive color starts with white (paper) and finishes with black; the outcome darkens as more color is applied.
