for both Dark and Light as suggested in this comment.

If you also want to add a predefined solarized color scheme, please feel free to go ahead and send a PR.

I imagine you'd add it right below this line:

termonad/src/Termonad/Config/Colour.hs

Line 126 in 0cd741d

deriving (Eq, Show, Functor, Foldable)

You could basically just copy this code into the Termonad.Config.Colour module:

termonad/example-config/ExampleSolarizedColourExtension.hs

Lines 44 to 69 in 0cd741d

	, palette = ExtendedPalette solarizedDark1 solarizedDark2
	}
	where
	solarizedDark1 :: Vec N8 (Colour Double)
	solarizedDark1 =
	sRGB24 0 43 54 -- base03, background
	:* sRGB24 220 50 47 -- red
	:* sRGB24 133 153 0 -- green
	:* sRGB24 181 137 0 -- yellow
	:* sRGB24 38 139 210 -- blue
	:* sRGB24 211 54 130 -- magenta
	:* sRGB24 42 161 152 -- cyan
	:* sRGB24 238 232 213 -- base2
	:* EmptyVec
	solarizedDark2 :: Vec N8 (Colour Double)
	solarizedDark2 =
	sRGB24 7 54 66 -- base02, background highlights
	:* sRGB24 203 75 22 -- orange
	:* sRGB24 88 110 117 -- base01, comments / secondary text
	:* sRGB24 131 148 150 -- base0, body text / default code / primary content
	:* sRGB24 147 161 161 -- base1, optional emphasised content
	:* sRGB24 108 113 196 -- violet
	:* sRGB24 101 123 131 -- base00
	:* sRGB24 253 246 227 -- base3
	:* EmptyVec

Just add a definition like solarizedDarkPalette and solarizedLightPalette. Then you can link to these two images you added in this PR in the haddocks. If you have trouble figuring it out you could send a WIP PR with what you have and we could go from there.

This would close #94.
