Simple answer is this markup which can be added to About Me bio box
<span style="position:absolute; top:0; left: 0; width:100%; height:130px; background-color:pink; z-index:2; mix-blend-mode:hue; pointer-events:none; display:block;"></span>
The magic happens due to mix-blend-mode CSS and here are other values which, in combination with background-color can visually change the top header section on Chaturbate.

mix-blend-mode: normal;
mix-blend-mode: multiply;
mix-blend-mode: screen;
mix-blend-mode: overlay;
mix-blend-mode: darken;
mix-blend-mode: lighten;
mix-blend-mode: color-dodge;
mix-blend-mode: color-burn;
mix-blend-mode: hard-light;
mix-blend-mode: soft-light;
mix-blend-mode: difference;
mix-blend-mode: exclusion;
mix-blend-mode: hue;
mix-blend-mode: saturation;
mix-blend-mode: color;
mix-blend-mode: luminosity;
