Just to clarify, Yellow Bunting is of course, yellow. On my screen, the flowers are orange (?) L. pumilum, which so far seems to be the likely candidate, I agree. Color variation is light orange to red, or yellow is rare. You might try supplying us with more to go by. Determining if it is a species or hybrid from a species can be difficult, too, especially without any other info.
How old?
Is it in a pot or in the ground?
Can I see foliage?
Are the buds fuzzy or shiny/smooth?
What time of the season does it bloom?
Where did you get it?
Is it supposed to be a hybrid? A species?
The more informative your question, the better the answer...
