It would be interesting to add support to add support to the old CIE's RGB color space (not to be confused with sRGB).

Related work:

• Creating CIERGB class in Litipk.ColorSharp.ColorSpaces namespace.
• Adding CIE's RGB color matching functions.
• Adding tests to cover the CIERGB class.

Chromatic Adaptation Transforms are needed in order to compute the spectrum's CRI (see #12), but also in other situations.

That's a work in progress, help and ideas are welcome, but this won't be a 'from scratch task'.

Adding CRI computation (for the spectrums) is a very important step, since it's one of the main milestones we want to achieve.

This feature isn't trivial, since it depends on another important and missing feature: Chromatic Adaptation Transforms (see #13).

Adding CQS computation (for the spectrums) is a very important step, since it's one of the main milestones we want to achieve.

This feature isn't trivial, I recommend to achieve CRI (see #12) computation in first place.

The SpectralWorkbench project has a nice API to retrieve and send light spectral information. It wold be nice if ColorSharp can use this API to interact with the SpectralWorkbench database.

The UCS word is used for many CIE color spaces, and the CIEUCS class is used to represent a deprecated color space, so it's better to change its name.

The CIEUCS class represents the color space from this article:
https://en.wikipedia.org/wiki/CIE_1960_color_space .

The current test suite is completely doomed. It sucks. I don't ask for help because it's my fault, in any case, this must be explained here to track the development process.

There are common illuminants missing in ColorSharp:

• D75 : North sky Daylight.
• E : Equal Energy Illuminant.
• F series : fluorescent lamps.

It would be interesting to add support to add support to the CIE's 1976 LUV color space (derived from the CIE's 1960 MacAdam color space).

Related work:

• Creating CIELUV class in Litipk.ColorSharp.ColorSpaces namespace.
• Adding tests to cover the CIELUV class.

Wikipedia article about this color space:

It would be interesting to add support to the CIE's 1964 UVW color space (Not to be confused with the CIE's 1960 color space, nor the CIE's 1976 color space).

I propose to name the class CIE1964 instead of CIEUVW because it's not a widely used color space and I think it's probable that some programmers use the wrong classes if we name it with its coordinate symbols.

Currently the ColorSharp's NuGet package only supports .NET 4.0.

It's easy to support another .NET version, but supporting multiple versions at the same time without MS Visual Studio isn't trivial.

It would be nice to have this feature to make easier to use ColorSharp.

RegularLightSpectrum.Equals fails to determine equality.
