If i knew what the colors were then maybe I could answer you.
They are colours that do not match
Although yellow is a component of orange, in this case neon orange and pastel yellow, would not be harmonious , they would clash-- big time. The brightness of a neon color would overshadow the softness of the pastel. If for some reason you must use them together, use the orange sparingly.

white,yellow and black
Lilac or violet

If the curtains and the drape are in the same colours, or contains the same patterns - yes, they match.
