According to shade filter concept, after absorption of certain wavelength, the remainder are reflected. This way, once red(near 600nm come 700nm) is absorbed, the rest should be reflected. And the rest combines together cyan, not green. Still I must be clear at molecular level.

You are watching: What color is the opposite of red

Because together per the literature and also complementary shade charts if the shade is specifically red climate you can gain complementary color as green yet if the the kind of red orange then you get the cyan.
I thick it also depends of various things including human perception as defined in the listed below article.

We must things in the right perspective as soon as we talk around such a transdisciplinar and facility issue together color. One point is come talk around colour regarding to irradiate (additive system) and other point is come talk about color regarding to pigments and painted surfaces (subtractive system). One point is to talk about color perception concerning to physiological , neurologic and mind activity, various other thing is to talk around cognition in emotional terms.
The major colors in the additive device (light) are Red, eco-friendly an Blue. For this reason the complementary color to Red would be a an additional color result from the mixture in between Green an Blue (Cyan).
The primary colors in the subtractive mechanism (pigments) room Cyan, Yellow and Magenta (or Blue, Yellow and Red if us follow Itten). For this reason the complementary shade to Red have to be the secondary color Green.
The basic colors to a system based on perception (NCS_Natural color System) room Yellow, Red, Blue, Green, White and also Black, because we refer to these colour to describe what friend see. Girlfriend don't to speak "this" color is a mixture between yellow and also Blue, you just say its Green.
Green is totally free to red. Yet it strongly depends upon red that exactly how red that is. Cyan deserve to be totally free to it but it relies upon the wavelength that red.
If you take the colorimetric interpretation and the literal an interpretation of complement, gift the colour that "completes" red, in other words mixes to white, then you draw a heat though the red chromaticity and also the white pointchormaticity and also see whereby it intersects the spectral locus in the green. For this reason it counts on precisely which red you room talking around and which white you are talking about. The greater the temperature the white, the bluer will be the safety colour. In the a signal red and also CIE conventional Illuminant D65 will provide a complementary that is blue-green, you room right.
The 2nd concept belongs with the art civilization and an extremely have a really different idea of security colours. I perform not ~ do so to know this concept!!
Complementary color: if the mix of a pair of shade stimuli give achromatic color, then the 2 colors space complementary to each other. 
Opponent colour are based upon Hering's opponent color theory i beg your pardon postulates three pairs that opponent color channels. 2 opposing bag of distinct hues are identified for the chromatic enemy channels: Yellow-Blue, Red-Green. Distinctive hue is a pure without any mix of the other colors, such as distinct Red: no greenish or bluish. Mixture the a pair the chromatic opponent shade is not declared to develop achromatic. Because that example, mixture same amount of unique yellow and unique blue will outcomes in white or gray, when mixture of equal amount of distinct red and also unique eco-friendly will be unique yellow. 
If you want to determine whether two colors room complementary colors: you deserve to measure the reflectance and plot lock in the chromaticity diagram under one CIE standard illuminant and standard observer. Additionally you can plot them in the foe based color space, favor CIELAB though it is no the perfect, to check whether lock are enemy or not.
You claimed the red ns assume it is distinct red, then the complementary color is cyan, and opponent color is green.
As mentioned previously the complement color depends top top the meaning of red color. Unfotunately our eyes space able to differentiate significantly more various "variants" of green than those that red. That is why a tiny variation the hue in red provides dramatic change of the match "green". In theory "pure green" have to be the contrary to contempt bluish red (close to magenta).
From mathematical point of view, cyan is the match of red color. That is acquired using two unary operators: complement and also negation.
Yes, red and also cyan is safety colors. In reality I wrote a record that tried to prove this. "The Yin and Yang of Colors" which have the right to be discovered here on mine RG-page
In the additive color system RED is R:255 G:0 B:0 and the complementary to this is R:0 G:255 B:255 (=cyan)
Please have a look at my symmetrical color model suggest 30 year ago: http://survivor99.com/colorforum/
A complementary color is not defined if friend don't define the illuminant of referral first. If you take a small red light with a top wavelength at 650nm, the complementary will be on the green side because that a reference illuminant in ~ 3000K, and also on the bluish side with a reference illuminant at 7000K. On usual computer display screens the white allude is usually close to 7000K or also more, for this reason the complementary of the red major is cyan, yet this is simply a details case.
Stephen john Dain and Adrien Gary Lucca gave good and near-complete answers for the additive totally free system. The complementary irradiate spectrum (i.e. Physical rather than physiological) absolutely depends both on the red and also on the white reference.
However, presume the viewer's vision is accommodated come the white reference, what matters is generally the spectral content of the red loved one to the reference.
So long as the recommendation has enough blue content that blue in a photo will appear blue, the match of a pure red will show up cyan. A purplish red (that contains some blue) will have actually a greener complement; similarly, one orangy red will have a bluer complement.
I've recently measured L, a and also b values considering CIELAB mechanism for the jelly confectionary products. How deserve to I recognize Chroma and also Hue worths for this products?
I have an image with two different regions. I desire to publish one an ar with a mixture of Magenta + Yellow i beg your pardon I have actually printed making use of red colour because M + Y = Red; however another region I want to print with cyan + black color colour. What colour mixture need to be usage on the photo so that cyan and black ink have the right to be jetted?
I am a student and also I am doing a project on a very interesting topic: why men and women perceive colors differently. But I am having a many trouble finding information. In assorted sources, the product is not easily accessible or is really unclear to an median student.

The only things the I’ve discovered were the eye anatomy and a physiological explanation (Bimler, 2004) the genes recognize the late of colors for this reason women heterozygous because that opsin genes watch colors much better than other women and men.
