Roses are red,
violets are NOT blue.
Who ever said they were is lying to you,
okay, maybe one can argue violets have a blue-ish hue,
but they are not all the way blue.
So stop saying violets are blue because that's not true.
Here's how it should go, so no more people are confused.

Roses are red,
Violets are purple.
