console.log(concolor`Ave ${'World'}(b,/blue) bold on blue`);
console.log(concolor`Ave ${'World'}(b,u,yellow) bold underline yellow`);
console.log(concolor`Ave ${'World'}(blue,u) blue underline`);
console.log(concolor`Ave ${'World'}(b,black/green) bold black on green`);
console.log(concolor`
Client on ${'192.168.1.1'}(black/green)

at ${new Date().toUTCString()}(b,blue)
`);const tag = concolor(styles);
console.log(tag`text`);Examples:
const warn = concolor('b,yellow');
const err = concolor('b,yellow/red');
const inf = concolor('i,white');
console.log(warn`test1 ${'text2'} text3`);
console.log(err`test4 ${'text5'} text6`);
console.log(inf`test7 ${'text8'} text9`);const style = concolor(styles);

const err = concolor('b,yellow/red');
const inf = concolor('i,white');
console.log(warn(`test1 ${'text2'} text3`));
console.log(err(`test4 ${'text5'} text6`));
console.log(inf(`test7 ${'text8'} text9`));const theme = concolor({
caption: 'b,white',
text: 'green',
link: 'u,yellow',
});
const caption = 'Caption';
