This higher energy is manifested in a change in colour of the light, making the object appear a different colour. It also changes the angles light is scattered from, making it appear to be a different shape.

Q. I'd like to know if "making" is a gerund or participle.

I would say it's a participle.

Does that make any difference in how you understand the sentence?

(Fascinating article.)

Thank you very much. Now I understand it.

It seemed to me that "a change in colour of the light" was in apposition to "making the object appear a different colour". So I thought that "making" might be a gerund.

Two things. One, I don't understand your use of the word "apposition" there. Two, what I got from the article was that scientists have discovered some amazing properties of light.

I'm not very good at English.
