lighten and darken with amount 0 are not returning the original color about color2k

Yeah that's definitely a weird result. I'll take a look later today this week.

My gut says that it's an artifact of parsing to HSL and then back to hex (rounding error?). Maybe there's a way to round there that doesn't cause this.

My schedule has been pretty hectic and I haven't really investigated too deeply into this.

Quick pulse check: how important is this issue to you? Do you have a specific use case where this result is undesirable?

Thanks!
