Woocommerce order fail

I have set up Woocommerce and am using Mijireh with the stripe payment gateway. I am on test mode and when I enter the correct card info everything works great but when I type the wrong info I get an error message “Whoops! Please fix the problems below:
Order failed. Please try again or contact the merchant for support.”….. This message is in black.. the same colour as all the other font on the page how can I make it red so its really obvious?? I have looked in the editor and I cant find it if someone knows how I can do it id really appreciate it.
