I can’t find woocommerce email style options

Hey, i an using Virtue theme and want to change styles of woocommerce emails that are sent when a customer does an order.
i looked other online guides. in those guides they have options to change email, header color, header picture, body color, etc. but in my woocommerce->settings->email i cant see those option. anyone having any idea why is the reason.

Thank you!
