How to apply custom fonts and icons to the ix-blind

I want to change the color of the ICON and font-size of the ix-blind as per figma.

Kindly provide the solution for this.

Expected behavior as per Figma:

Hello @papaiahikkurthi, why do you need to change the font-size? The icon color is automatically adapted to the blind header background to provide enough contrast in order to ensure readabilty, therefor it cannot be overwritten.
