Which is better to interpolate from one color to another?
You can do RGB interpolation, but the results are better with HSV, because in this space color is separated from luminance and saturation (Wikipedia article on HSV). HSV interpolation is more “logical” than the RGB one, because with the latter you can get extra colors while interpolating.
How to interpolate one color to another in RGB?
To expand on “you can get extra colors”… in RGB, for example, linear interpolation from blue to yellow goes unintuitively through neutral gray; HSV goes either through green, or through magenta, red, orange. So you’ll get extra colors either way.
How does linear interpolation work in three dimensions?
If it’s true that linear interpolation works as expected in three dimensions, the same cannot say for colours. There’s a fundamental difference between the XYZ and RGB spaces: the way the human eye perceive colours. While it make sense to connect two points in a 3D space with a line, the same doesn’t always apply for points in the RGB space.
How to interpolate from one color to another in JavaScript?
I have adapted Synxis’s C example (above) into an executable JavaScript program. The program interpolates the color yellow, from red and green. The input and output is in RGB-space, but the interpolation is handled in the HSV-space.
Why do you use HSV for colour interpolation?
The HSV colour space corresponds much more closely to colour as it is perceived by humans – if you want a “natural” interpolation between two colours you therefore want to use a colour space that varies in an appropriate way – e.g. you don’t want the perceived brightness to change as you interpolate.
Can a hue be rotated around a color wheel?
The hue was accurately rotated around a color wheel, but if you look closely at the color changes, we should see colors very similar to the perimeter of the circle in the first example of this article, where we can very clearly see each bright color from a rainbow — red, orange, yellow, green, blue, indigo, and violet.
Is there a way to animate a hue?
Even though the hsl () color function allows us to specify hue, saturation, and lightness levels individually, there is no straightforward way to animate one value independently of the others.
