There are many hundreds of light coloured minerals and it is likely that your specimen isn't one of the common ones featured in this key.
If you want to find out more about your mineral you could search the
Virtual Store which features a range of different minerals, or could do some research at your local library. You could also take your specimen to a local museum to compare it with their mineral collection.
