Colour can be described in terms of hue (dominant wavelength of the visible spectrum), saturation (the amount of white light mixed in with a hue) and brightness (intensity of light). Any desired hue of light can be produced when various amounts of the three primary colours of light (red...
Because of this, certain colours are easier for us to see and understand. “And chartreuse is the colour on the spectrum most visible to the human eye. So it’s a great design decision to use that colour as a call to action or accent an area that you want to draw attention to,” ...
The colour of the clear sky or the deep sea, between green and purple in the visible spectrum, and one of the primary additive colours for transmitted light; the colour obtained by subtracting red and green from white light using magenta and cyan filters; or any colour resembling this. Blue...
The colour spectrum is made up of three primary colours: red, yellow and blue. By combining these three colours, secondary colours – green, violet, and orange – are produced. Mixing any primary or secondary colour produces a tertiary colour – blue-green, blue-violet, red-violet, or...
A very small segment of the EM spectrum, termed the visible spectrum, roughly 390 (violet) – 710 (red) nanometers (nm), is what humans are able to perceive. Other organisms can see other EM waves. Ourcats, dogs, and hedgehogs can see UV light, and insects use their UV vision to ...
colour you could imagine (mainly white led streetlights, plus yellow/orange and magenta leds in greenhouses) + still HPS. Flower growers experiment with different "light spectrum recipes", but the details of the spectrum are kept secret. The colours and intensity may chang...
It takes a good eye to find the right amount of saturation. Too strong of a color and you end up with a jarring contrast with the black, like yellow with black. Too weak of a color and you end up with a muddled combination, like navy and black.How to strike the right balance? Not...
As Ryan Gosling’s character enters the dust-filled protein farm, there’s oodles of detail in the wind-swept barren landscape. The projector offers realistic but vibrant colours, with the reds of Sapper Morton’s suit popping from the otherwise grey shot, without looking overcooked. (Image ...
... Some consider white to be a colour, because white light comprises all hues on the visible light spectrum. And many do consider black to be a colour, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colours, they're shades...
What features would make these visible from space? Hint:What would help you identify something from really far away? The following images show amazing colours and patterns that might be related to the biosphere. Most of them were captured by Sentinel-2!
