My wisteria was a lovely yellow in the spring but has gone completely green. What can I do to get it back to the yellow colour it was?

Are you talking about the leaves or is this a yellow flowered wisteria?
If you are talking about the leaves, they aren't suppose to be yellow. This indicates a health issue with the plant. Once the issue is corrected, it returns to a green and healthy leaf color.
If you have a yellow flowered wisteria, it will rebloom next spring. They bloom in early to mid spring and are green for the remained of the season after the flowers fall.
