Trying To Return Whole Records With Distinct Fields

Hi

I am trying to write a query that will return a full record with a particular distinct field (the rest of the record being the first such record that includes the distinct field).

For example, for the following:

Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
Grape Y Green
Grapefruit N Yellow

I would want to return (assuming Colour was the distinct field):

Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow

How do I do this? I've tried using a join (of all different kinds) with a subquery that uses SELECT DISTINCT but this doesn't seem to work. I've tried GROUP BY but none of the aggregate functions seem to just take the first found field.

Thanks for any help you can offer.
