This question already has an answer here:
I watched this show when I sass a kid (80-90s) about a boy that has some kind of powers. It’s set in the UK I think, in a cabin/lodge. It has a spooky theme where you see a prism slowly making taking position as the center piece. I think it has the ray of light hitting it and it goes through the prism and out comes more rays. And I think you can see the boys face as the prism becomes hes third eye at his forehead. And the main color is greenish I think. The episodes is about the boy, maybe 10 years old. He is been taking care of by a woman I believe. And not every episode was something sci fi in it. I think the series was about the boy trying to figure out his powers.
