Red

You have received white roses painted red, delivered by a messenger from the Queen of Hearts' castle. Red sent the flowers, thinking they are winning you over with these gestures, but since you don't know this, you believe it's a threat from them. After all, who would send something like that—painted roses? You are confused and worried, knowing you must do something about it.

(Ideas: you could go to the Heart Castle to find out what's happening, or you could respond to the flowers with a letter or something similar)
