This post includes dupe and comparison swatches and information for select colors from MAC’s Hey, Sailor! Collection.
Some of the swatches are for colors that are very similar and others are of colors in the same family, though they won’t be “dupes.”
There are plenty of colors out there that are similar but aren’t shown below, so if you have a color in mind that I don’t mention, run an image search for it. There are also tons of other people out there who do comparison swatches, so I encourage you to hunt around.

It would be a full time job (probably more than a full time job) to find dupes and comparisons, especially for MAC (or cross-brand…a nightmare!)…thanks for taking the time to do some!
It definitely would be. You’re welcome!
This was very helpful.
Thank you!
