tip: for a coloured profile overlay

if you want your profile to have a coloured overlay (like mine, or that one terminal theme with the green overlay), paste the following right below the style tag at the top of your code

html {
filter: grayscale(100%) sepia(100%) saturate(300%) hue-rotate(223deg);
}

the "hue-rotate(223deg)" makes it purple. if you want a different colour, play around w diff numbers until you find something you like
