Hugo,

Thank you for sharing your code examples.

> I found a Microsoft article on how to change from RGB to HSL and I wrote a Color class to deal with several of this types of transformations

Here's an interesting link from Sergey as posted in Thread #967748.

How To Converting Colors Between RGB and HLS (HBS)

> I use the Hue trick to highlight the selected record in a grid when the backcolor depends on the records, for example some records are red-ish some are green-ish etc, the to highlight the current color I change the HUE to make the selected record brighter.

What a great idea! I always wondered how some applications managed to do this.

Thanks again for your help, Hugo!
