This leaves green, i. Where the yellow and magenta overlap, we see the subtractive mixture of yellow and magenta. In other words, we see white from which the yellow filter has subtracted blue and the magenta filter has subtracted green. This leaves red, i. Where the magenta and cyan overlap, we see the subtractive mixture of magenta and cyan. In other words, we see white from which the magenta filter has subtracted green and the cyan filter has subtracted red.
Finally, where yellow, magenta and cyan overlap in the centre, we see the subtractive mixture of yellow, magenta and cyan. In other words, we see white from which the yellow filter has subtracted blue, the magenta filter has subtracted green and the cyan filter has subtracted red. We return to Subtractive primaries and Subtractive colour mixing below. The illustration at left shows several different colours. The numbers are six-digit hexadecimal representations of RGB colours.
Decimal goes from 0 to 9, hexadecimal extends this 9, a, b, c, d, e, f, to give 2 4 values per digit. The colour saturated red is usually written ff, but could also be written in decimal: ;; The first two digits are the brightness of a red pixel, the next two that of the green, then that of blue. The right hand part of the picture is a close-up of a computer screen, which magnifies the red, yellow, white, magenta intersection.
Looking at the right picture, at top left we see that only red components of each pixel are lit. At top right, both red and green are lit and, from a distance, these appear yellow as in the picture at left. At bottom right, red, green and blue are all lit and the combination centre of left picture is a convincing white. If you have the room to move ten metres or so back from your screen, you'll see that the sections of the picture on the right really do become red, yellow, white and magenta though the white is less bright than the surrounding white.
If you'd like to examine this more closely, here are original close-up photographs courtesy Noel Hanna for the same illustration shown on a computer monitor and a smart-phone. If you download these files, you can zoom out or in or walk backwards and forwards to see the effect. The photoreceptors in your retina that respond to colour come in just three varieties, which we call 'red', 'green' and 'blue' according to the colour which produces maximal response.
On the diagram at top right, the proportional response of the 'red', 'green' and 'blue' photoreceptors is shown as a function of wavelength. A three-colour representation of a spectrum is shown below the graph. Suppose that light from the yellow region of the spectrum, with a wavelength of say nm, arrives at the retina. It lies between that of red say nm and green nm , so this light stimulates both red and green photoreceptors.
This evokes a sensation that we are taught to call yellow. However, yellow that you see on the monitor is not light with wavelength near nm. Instead, the monitor makes yellow colour using red light and green light from the same pixel. These two different wavelengths from the monitor are focussed onto a small area on your fovea, where it also stimulates red and green photoreceptors.
So we perceive the effect as similar to light with wavelength nm, even though no light of this wavelength is present. Looking at their placement on the RGB color wheel, when red and green are mixed together, they make the color yellow. Every preschooler knows that Red, Blue, and Green are primary colors.
And since Red is a primary color that means it can not be made from either Green or Blue. But surprise! Red can be made by mixing the other set of primary colors. Give a child some Magenta and Yellow paint, and Voila! However, you can actually use red and green together in your home decor in a way that will look good all year round. Green and red are a classic combo. This mixture of colors is loved by many people. You just have to choose the right shade from each and style them together nicely.
This outfit above is a really good example of red and green tones that go well together. Accent colors that work well with green are yellow, red and orange; blue, purple, violet and pink. Definitions of dark-green. Grey and green. Grey is the perfect neutral when combined with a splash of colour, it can really bring a room to life — especially a vibrant green. Associated with nature this revitalising shade can perk up all shades of grey, from soft almost lilac tones to more brooding charcoal tones.
Warm greens are commonly called names like olive, khaki, chartreuse, lime, pistachio etc. To cool green down and make it cool, add blue to get a bluish-green. Cool greens are often called names like forest, emerald, bottle green, seafoam etc.
