RGB Hex values don't match Nord palette values

[ericvw]

I noticed when looking at my iTerm 2 settings that the RGB Hex values for the Basic and ANSI colors don't match precisely with the RGB Hex values described in https://www.nordtheme.com/docs/colors-and-palettes.

For example, Background (nord0) is set to #2e333f, whereas I was expecting #2e3440. The other colors were ever so slightly off as well.

I cross-checked the values and have a patch that aligns the values. I have a pull request to follow shortly…
