RGB Colors

Using RGB colors gives you the full range of over 16 Million colors to use in your terminal. We won’t provide an example for each color but here are a few to give you an idea of how it works.

subject do
  paintbrush do
    "#{hex_f00 'R'}#{hex_ffa500 'A'}#{hex_ff0 'I'}#{hex_080 'N'}" \
    "#{hex_00f 'B'}#{hex_4b0082 'O'}#{hex_ee82ee 'W'}"
  end
end

it 'outputs a rainbow' do
  expect(subject).to eql(
    "\e[38;2;255;0;0mR\e[0m\e[0m\e[38;2;255;165;0mA\e[0m\e[0m" \
    "\e[38;2;255;255;0mI\e[0m\e[0m\e[38;2;0;136;0mN\e[0m\e[0m" \
    "\e[38;2;0;0;255mB\e[0m\e[0m\e[38;2;75;0;130mO\e[0m\e[0m" \
    "\e[38;2;238;130;238mW\e[0m\e[0m"
  )
end

        

RAINBOW

Note that both the full hex code and the abbreviated versions are supported, i.e. hex_ff0 produces the same output as hex_ffff00:

subject { paintbrush { hex_ff0 'yellow' } }

it { is_expected.to eql(paintbrush { hex_ffff00 'yellow' }) }

yellow
