No. Just like in real life and in various forms of storytelling, in Roblox scary stories, roses can be different colors. Some might use purple roses to signify mystery. Also, a story could feature roses that have lost their color due to a curse, which could be part of the horror element, making them seem more 'dead' or lifeless compared to the vibrant red roses we usually associate with roses.
No. While red roses are a common and perhaps stereotypical representation, in the creative world of Roblox scary stories, roses could be any color. Writers and creators might use black roses to represent pure evil or death, or white roses which could seem innocent at first but be part of a more sinister plot.
Not necessarily. In Roblox scary stories, the color of roses can be used to subvert expectations. For instance, a blue rose might be used to symbolize something unnatural or otherworldly. It all depends on the storyteller's intention. They could even have roses that change color depending on the situation, like turning red when danger is near.
