How to use the common-tags.replaceSubstitutionTransformer function in common-tags

	bright: 'rgb(255,255,255)',
	bob: 'black lighten 50 saturate 50 spin 180',
	ul: 'underline',
	invert: 'invert',
	exBackground: 'background dark red',
	exBold: 'bold yellow',
	exFaint: 'faint yellow',
	exItalic: 'italic #33FF33',
	exInvert: 'invert #7B00B1',

	exBlink: 'blink orange'
}))

export const colorReplacer = new TemplateTag(
	replaceSubstitutionTransformer(
		/([a-zA-Z]+?)[:/|](.+)/,
		(match, colorName, content) => `${clr[colorName]}${content}${clr[colorName].out}`
	)
)

export function spectrum(width, char) {
