Mike, logo above is the lavender you asked for (which I, personally, think looks like baby shit in a French whorehouse...
:o) just my opinion).

Below is the darker lavender, same as button two when the mouse is not over it. This is very close to Pantone Violet C which you specifically told me not to use for the logo because it is too blue when we looked at the color samples in your office.

For comparison, logo below is the exact color (Pantone Purple C) you picked when we looked at the PMS samples in your office last week.

And logo above is the last color we looked at Friday after I darkened the logo up a bit. The original color was a bit brighter. But I think I got the hue about right, based on our meeting.

Logo below is Pantone Process Blue (cyan).

Logo above is 30% Process Blue that we have used on the brochure and in ads.

Here is a set of swatches for colors grading from the violet button (#2) to the blue one (#5).

Let me know what you want.

Here are some spheres:
