Conversion RGB to xyY with colormath

Asked 2021-Jun-08 at 13:40

With colormath I make a conversion from RGB to xyY value. It works fine for 1 RGB value, but I can't find the right code to do the conversion for multiple RGB values imported from an Excel. I use to following code:

convert_color is expecting floats and you're giving it dataframe columns instead. You need to apply the conversion one row at at time, which can be done as follows:

Conversion RGB into LAB for multiple values

Asked 2021-Jun-07 at 12:55

I wrote a code that gives me the average RGB value of an image. Now I want besides the RGB value, also a LAB value. I found a code to do the conversion, but when I run the code, it only gives me the last value.

So with this code I receive the average RGB and place it in a dataframe:

Short Answer

Check this question (possible duplicate).

More details on the official documentation.

Long Answer

Use these formula to get your own conversion.

Please keep in mind that there is not a single Lab (depending on the CIE you use), so you might want to tweak the values if necessary.

How to resolve a Maven dependency of type pom?

Asked 2021-Feb-15 at 22:41

I am trying to import a library in Maven which is Kotlin Multiplatform.

This is it's Github repo (does not actually matter much of course)

Point is, it says it can be imported in with this dependency for Gradle:

The link to the Maven Central from GitHub points to a bare POM artifact, without any dependencies and/or attached JARs.

It looks like Kotlin MP uploads JVM-specific artifacts with a different artifactId - colormath-jvm in this case. Please check corresponding directory in the Maven Central.

I suggest using following dependency declaration in the POM:

QUESTION

Better algorithm with CIEDE2000 to find true opposite colors

Asked 2020-Jul-18 at 22:52

Using Python 3.7 and the colormath module, I had some fun trying to find the complete opposite of one color (ex. The opposite color of black [0, 0, 0] is yellow [255, 255, 0] with a DE of 101.20397657762743) or trying to find the two colors with the most color difference (i.e. "Navy" [0, 0, 110] and "Chartreuse" [143, 255, 0] with a DE of 119.4740815993416, from my potentially inaccurate testing).

Unfortunately, the only way I have found to find the opposite of a given color is just to bruteforce with a little bit of optimization by comparing the given color with (almost) every single sRGB color combo (or, [0, 0, 0] to [255, 255, 255]).

Python 3.7 code:

CIE DeltaE 2000 is not appropriate for large colour differences so large differences in the range [10, 20]+ simply cannot be evaluated with this quasi-metric and you should probably look at something else such as HyAB colour difference metric: https://onlinelibrary.wiley.com/doi/abs/10.1002/col.22451 or alike.

Find color temperature from spectral response

Asked 2020-Jul-07 at 22:03

I search for some Python library that can find color temperature from spectral response from spectrometer. I have single spectrum output like this:

I want to find color temperate of my light source.

The outputs shuld be like here (values not plot):

I searched a lot but I didn't find anything, in libraries like colour-science or python-colormath I don't see option like that. Is it possible at all?

...

ANSWER

Answered 2020-Jul-07 at 15:16

The process normally takes the following steps:

Convert the spectrum to a CIE XYZ value
Convert the XYZ value to RGB using a specific CIE color system
Apply gamma correction

There is an explanation and code here.

ANSWER

Answered 2020-Jun-30 at 20:53

I suggest you to use this website to:

insert the LAB values
check the RGB values that the website gives you
check the color associated with the LAB/RGB you have insert

I have done a check and the conversion between the two matrix you wrote is correct.
For example let's try with the second element of the list above, which it should be labeled as blue-violet flowers:

How can I use a specific version of a Haskell package with Nix?

Asked 2020-Feb-18 at 15:51

I just want to be able to use the latest version of pandoc, the Haskell package, in my project which I'm building with Nix.

Here's my shell.nix file. The commented-out section is where I attempt to override the package version, but it doesn't seem to work.

Pandoc 2.9.1.1 is available in nixpkgs as haskellPackages.pandoc_2_9_1_1. I'd advise you to use this instead of trying to override the package as there are some differences in dependencies. For reference though, here's how you would go about overriding haskellPackages:
