Burnt Sienna

Of all the colors in the box
I chose Burnt Sienna.
 
Of all the things Crayola can burn,
It chose to burn sienna.
 
What even is sienna?
An animal?  A person?
 
Can sienna even be burnt?
Can it be set on fire?
 
And aren't burnt things black?
Or red and swollen?
 
Of one thing I am sure--
Burnt things
Are never
The brownish color
Of Burnt Sienna.
 
I Googled sienna
And it's a type of car.
 
I'd like mine in blue, please.
