Alpha values of RGBA color tuples are ignored

See original GitHub issue

Thank you very much for providing this awesome library. Unfortunately, I found a bug concerning the handling of the transparency values in RGBA colour tuples. The alpha value is simply being ignored, as

print(sns.color_palette([(1,1,1,0)])) only results in the following output:

[(1.0, 1.0, 1.0)]

Thank you very much for your reply. I would still prefer to be able to set the alpha value myself. Otherwise, I wouldn’t, for example, be able to create a scatterplot with varying degrees of transparency for different categories.

Related to that, it would maybe be a good idea to change the following line of code: https://github.com/mwaskom/seaborn/blob/88479dc3a9c5dee00fa697fda73152add0827fc4/seaborn/relational.py#L937 to allow for setting the alpha value in relation to the hue value. What’s your opinion on that?

I subscribe also to this feature request.

It is something that is missing in the current seaborn package
