I did it in Gimp in the end as follows (thanks, Gimp listers):

*Create the base of the inverted HSV cone*

1    Use the ellipse selection to create a circle selection on a white
background.  (You might want to set up guides to locate the centre of
the circle.)

2    Click the Blend tool, set the Gradient to  Full Saturation Spectrum
CCW, and set the Shape to Conical (asym).

3    Click the centre of the circular selection and draw a radius.  You
now have a circle filled with a coloured cone.

4    Set the foreground colour to white.

5    Change the Gradient to  FG Colour to Transparent and Shape to
Radial, and draw another radius.  If the perimeter is not quite
saturated enough, copy the FG Colour to Transparent gradient and adjust
the copy so that the transparency sets in earlier.

6    Change the proportions  so the circle becomes an ellipse, longer in
its horizontal axis.  This is the base of the inverted cone.

7   Add an alpha channel to the ellipse layer.

8   Change the foreground colour to black, then use the Bucket Fill tool
to change the four white corners of the ellipse to black.

9   Choose Select > By Colour, click the black,  and cut the black
selection.

*Create the cone*

The cone will make a tangent to the ellipse a little around the bottom
curve from the ends.  So you will first need to copy the Full Saturation
Spectrum CCW gradient and adjust the copy's end colours to match those
at the point of the tangents.

1   Create a new document with a square selection on a white background.

2   Change the blend tool to Gradient: Custom copy of  Full Saturation
Spectrum CCW.

3   Drag the blend tool horizontally from the L to R side of the square.

4   Press Ctrl+a to select the entire square.

5   Click the Perspective tool.

6   Drag the bottom L and R handles to the vertical centre line, keeping
the horizontal grid line horizontal.  You don't need to exactly place
the L and R corners at the centre, as this is fixed later, as long as
the general effect of the bands of colour fanning out from the point on
the bottom edge to the full width on the top edge is achieved.

7   Set the foreground colour to black.

8   Click the Blend tool and set Gradient to FG Colour to Transparent,
and draw from the "point" bottom edge to the centre of the full width
top edge.

9   Click the Bezier tool and draw an inverted triangle from the top L
corner to the bottom centre, the top R corner and close the curve.

10  Change the path to a selection and copy the selection.

11  Make a new layer under your ellipse in the first document, paste
your inverted coloured triangle into that layer, and move it around
until the sloping sides are tangents to the ellipse.

The colours in the inverted triangle don't quite match up with those
along the bottom edge of the ellipse but the effect of the HSV inverted
cone is good enough to fool a fast moving observer.

Hi everyone,

I've joined to inform the moderator that GIMP is being sold on ebay.  
The link to the seller is http://stores.ebay.com/Info-Injection  If
this person has permission to sell the program I humbly apologise for
troubling you.

Thank you,

What makes you think there would be anything wrong with that? The GPL
says: "You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in exchange
for a fee." As far as I could see from the silly website, the price
was very reasonable and certainly is covered by "charge a fee for the
physical act of transferring a copy".

Sure, I do find this business model immoral, and I feel sad for the
suckers who pay even just $5 for something they could download for
free. Why buy GIMP from somebody who as far as I can see offers no
added value (like support, or bundled additional instructions, bundled
additional brushes, patterns or whatever? But then, you get what you
pay for, people who believe the crap on that website ("can do
EVERYTHING Photoshop can do") and think that it looks professional and
trustworthy, probably get screwed over all the time, not much we can
do about that.

> If this person has permission to sell the program I humbly apologise for troubling you.

Anybody has permission to sell (or give away) GIMP. That is what Open
Source means. For GPL licensed software (like GIMP), the only "catch"
is that you have to provide the source code, too (or offer to provide
it upon request) (read the license for details, and consult legal
expertise). Whether this "Info Injection" does this or not, no idea,
and I don't care, and I doubt the other copyright owners are that
interested in using/wasting time on finding out either.

It is one of the basic principles of Free Software that everyone does have the right to sell it - if he does follow the terms set by the software's license while doing so. For GIMP, this license is the GNU GPL.

The outline is described here:
http://www.gimp.org/about/selling

For more in-depth information, you could go to http://www.gnu.org/philosophy/selling.html

The prices for the CDs seem to be reasonable.

It is allowed and bear in mind some people may have a very slow or
troublesome connection and might prefer to install from a disc.

I've also seen Gimp bundled with other free programs to tempt buyers!

This is legal if the product offered abides by the
software license.
If the software was obtained from the GIMPVS web site, this will
be illegal since the GIMPVS team won't be supported this anymore ,and
as stated is no longer distributed on author request.: If this is a GIMPVS
release, this is illegal.

Are you trying to tell me that - while being derived from GIMP - GIMPVS has been distributed or is distributed under a license different from the GPL?
