interval = 4000
for(i=1;i<20;i++){
    setTimeout(d1,i*interval);
    setTimeout(d2,i*interval+(interval/5));
    setTimeout(d3,i*interval+(2*interval/5));
    setTimeout(d4,i*interval+(3*interval/5));
    setTimeout(d5,i*interval+(4*interval/5));
}

 d0('green')
}

function d2(){
console.log('\x1Bc');

function d0(col1){

CFonts.say('    LOVE     ', {
    font: 'block',              // define the font face
    align: 'left',              // define text alignment
  //  colors: ['red'],         // define all colors

    lineHeight: 1,              // define the line height
    space: true,                // define if the output text should have empty lines on top and on the bottom
