    I'm tempted to forward your color experiments to the german Twizy

    <br>
    Try adding a 1-2 bit feathering on the magic wand selection for the
    colour mask, that should eliminate the remaining border.<br>

      I've spent some time trying this tonight.
      <div><br>
      </div>
      <div>I took the basic twizy image, magic wand selected the paint
        colour part of the vehicle, then cut and paste that as a new
        layer. I then converted the paint colour layer to grayscale.</div>
      <div><br>
      </div>
      <div>Next, using the colorise filter, applied to the grayscale
        paint layer, I tried colouring it with a colour wheel. It worked
        beautifully. I could generate all the possible colours, and the
        paint highlights and shadows looked really good.</div>
      <div><br>
      </div>
      <div>I'll now see if I can do this programatically in iOS. If I
        can, we can dramatically reduce the amount of artwork required
        for each vehicle. Just a couple of base image layers and a
        4-byte ARGB code for each standard vehicle (plus a colour wheel
        for users to choose their own custom colour).</div>

                this, but not being in any way proficient with
                photoshop, I'm not sure if it is possible. Can we
                somehow have a base layer of the solid bits of the car,
                then an overlay layer colour mask. Then, somehow apply a
                colour slider to the colour mask layer to generate the
                different colour variations of the car? That way, we
                would only need 1 image for each car (ok, two images: a
                base layer and a colour layer), but could generate any
                colour we want in the App itself (including custom
                colours) just with a colour-wheel (as well as provide
                stock colour choices). Rather than the current approach
                of just an image filename, this would become a base
                vehicle type and RGB colour selection. Any photoshop
                experts know how to do this?</div>
              <div><br>
              </div>
              <div>That wouldn't solve the problem of custom car
                artwork, which we would still have to allow for, but
                would (a) dramatically reduce the number of images for
                each car required, and (b) allow for custom colour
                variations.</div>
