Thanks Charlie. I have already worked on finding the closest color. It is through the RGB space transformation to HSB space transformation and then finding the closest distance.
The min distance for RGB doesnt give good results.

Kulvinder, I don't work for Google, but the list that was posted (and which seems to work) is: "#0D7813", "#1B887A", "#29527A", "#2952A3", "#28754E", "#4A716C", "#4E5D6C", "#5229A3", "#528800", "#5A6986", "#6E6E41", "#705770", "#7A367A", "#865A5A", "#88880E", "#8D6F47", "#A32929", "#AB8B00", "#B1365F", "#B1440E", "#BE6D00". Finding the closest match for a given color is relatively straightforward: just calculate the distance in RGB colorspace (sqrt((r2-r1)^2 + (g2-g1)^2 + (b2-b1)^2)) between each of the colors above and the color you're trying to match, then choose the color with the smallest distance. Maybe more work than it could be, but it's good to stretch those CS101 muscles every now and then, right? :-) Regards, Charlie On Aug 16, 12:11 am, Kulvinder Singh <[EMAIL PROTECTED]> wrote: > Can anybody from Google reply on this ? > > I think untill and unless we have a list of colors available and since Google > APi doesnt seem to accept "any" color, the Calendar Add feature is not useful > at all. > > Thanks----- Original Message ---- > From: Dave <[EMAIL PROTECTED]> > To: Google Calendar Data API <[email protected]> > Sent: Thursday, August 16, 2007 7:47:49 AM > Subject: Re: How to find the colors available for Coloring a Google Calendar ? > > I guess this error means I have to pick from that list, and only that > list?
