Change that rhyme

roses are red
violets are violet
don't say they are blue
or else you must be stranded on islet

roses are red
violets aren't blue
this may be dissapointing
but it is true

roses may be red,
Violets aren't blue
change my mind
And ill upvote you

Roses are red
Violets are blue
The fact that violets are blue is a lie
Because they're violet
