Change color of a specific word generated by script [closed]

Insted of

<font style="font-color:#2ED7A2;">' + crypt_single_target_currency.match(/.*?\(([0-9a-z]+)\)/i)[1] + '</font>

try

<span style="color:#2ED7A2;">' + crypt_single_target_currency.match(/.*?\(([0-9a-z]+)\)/i)[1] + '</span>

the font tag isn’t supported in html 5 and you were calling “font-color” instead of just “color”
