Alpha transparency

[ben-eb]

Just leaving this as a note to get back to when I (or anyone else, PR welcome) have time.

There should be an option to ignore alpha so #000 and rgba(0, 0, 0, 0.3) are considered different.

[captbaritone]

I would expect this to be the default behavior.

[SlexAxton]

@captbaritone do you have a suggestion on how to implement it safely?

#000 and rgba(0,0,0,0.3) may be exactly the same, or very different depending on the color of the element behind it.

[Sigiller]

Can we just multiply diffAmount by the difference between the alpha сhannel values of colors?

@Sigiller @kbytin @XOP do you want to send PR for it?

not in the nearest future, sorry
