This quote from the article:

“Compare red nail polish to red ink: both are red, but the nail polish will be visible on black paper because it reflects light. The ink won’t be, because it absorbs light.”

doesn't seem right to me, but I'm not an expert. The ink doesn't reflect light? If you put a drop of red ink on a sheet of glass, it won't look red? Isn't the difference because the ink will soak in to the paper while the polish will sit on top of it?

I wonder if CMYK would be appropriate? The article didn't mention anything about it (even though it talks about how they tried a bunch of other color spaces by name)

CMYK is an subtractive color model, it is not very understandable and definitely not intuitive for human color perception. HSL is much better for that. It all is not too revelant in the end result I think because those are just models and their software exposes certain aspects of colors.

Ink mainly changes the color of light that passes through it. Nail polish absorbs and reflects light at its surface. If you look at a deep pool of red ink, it looks pretty close to black because it mostly absorbs light instead of reflecting it. The wording could be clearer though.

Make no mistake, this level of attention to detail is why this app has remained consistently in the top charts since its release.

It's on the charts because it's "free". The overall rating is only 4/5 stars on itunes. They use the annoying model of making you buy tools like color as in app purchases.

Notability, which has some similarities, sells for 0.99 without in app purchase nonsense and is rated higher.
