the grey text? you'll have to remove "text-muted" and add in style="color: HEXCOLOR;" to the line you want coloured text.

If you want ALL of the text to be purple, replace:

<div class="mx-auto text-muted my-3" style="max-width: 720px; font-size: 12px; letter-spacing: .6px;">

with:

<div class="mx-auto my-3" style="max-width: 720px; font-size: 12px; letter-spacing: .6px; color: #7F7DD4">
