Is it possible to change the color of from address when sending marketing emails from Marketo?

[KB2024]

Hi Everyone,

We are wondering if it is possible to change the color of the FROM address on our marketing emails so that the recipient will see the from address in a different color, rather than default black text? We are hoping to change it to be green if possible. Does Marketo allow this? I have attached a screenshot (below) as an example. 

Any tips or suggestions would be appreciated! Thank you!

No. Headers (From, Reply-To, Subject) are text-only. You cannot apply formatting.

This isn't a Marketo restriction, it's true of all emails.
