How to change button color (error function)?

Hello!

I used the following code to change the color of the button.

/* CF7 submit button */
input.wpcf7-submit {
    background-color: var(--global-color-11);
    height: 58px;
    font-size: 16px;
}

But when an error is raised, the color of the button returns to the standard one.
Example: https://prnt.sc/G_nfwnsJR-Hd
Example (with problem): https://prnt.sc/PAB5Ny2cqtft

Tell me how to change the color from green to red (as in the first example)?

Respectfully yours, Pavel
