Love this tool, but just wanted to point out that there is a little problem in calculating the colours. I'll give you a couple of examples.
Using the tool, lightening or darkening a color by 0 changes the color, when it should actually remain the same.
Lighten by 0 gives #133659
Darken by 0 gives #123354
And sticking with #123456, darkening it by 10% with SASS gives #091a2c, but your tool returns #09192a.
Thanks for the heads up @Aptary - I suspect this is mostly due differences in how JS and Ruby treat numbers / math. Will update our tests and see if we can't get it sorted out.
I'm having the same problem. It seemed like just the tool I was looking for, until I started using it and I kept getting values that were not the same between this tool and sass. :(
SassMe: lighten(#7EB9E8, 26) --> #f2f8fd
Sass: lighten(#7EB9E8, 26) --> #eff6fc
Yep, same problem here. :(
SassMe: desaturate(adjust_hue(lighten(#444346,22),3),1) -- > #7c7b7f
Sass : desaturate(adjust_hue(lighten(#444346,22),3),1) -- > #7c7b7e
Pull requests welcome.
The project now lives under my github jimniels/sassme (and is live at jim-nielsen.com/sassme. Any suggestions, issues, improvements, or PRs are welcome there :)
