16. It is sedimentary and opaque. It is a shade
redder than their Cobalt Violet. <br><br>
Graham's cobalt violet is close in looks to Daniel Smith's Cobalt Violet
deep. Unlike most Cobalt Violet watercolors, it flows evenly and
isn't gummy like some brands. I am in love with it. If you
are looking for the lighter version of what most manufacturers Cobalt
Violet looks like in a Graham paint, go with their Ultramarine
Pink.<br><br>

<font size=2 color="#000080">Pat’s information is right on the
mark. Mineral or Manganese Violet is very different from Winsor or
carbazole violet (=dioxazine purple). Mn Violet is lighter in value
and more interesting in texture by far, but you cannot get very dark with
it. <br>
<br>
My Daniel Smith is somewhat duller than cobalt violet, which is also
fairly light in value, nice in texture, somewhat warmer. I think
that, except for delicate florals, you are much better off with the
ultramarine/rose mixture suggested in Handprint – much more
versatile. Mn Violet is not worth the money, unless you want its
special delicacy and textural effects, and I would prefer Co Violet in
those cases, if you are happy with the warmer hue.<br>
<br>
M.Graham is bringing out a mineral violet in their new additions, but I
haven’t had a chance to test theirs yet.<br>

Hi, Miriam<br><br>
I went to the paints section at Handprint and below is the information I
got. Mineral violet is the Maimeri name, but apparently it is PV 16 so
the same pigment is used as shown by other manufacturers. I have not used
any of these personally, however, so there may be differences.<br>
<br>
FWIW<br>

</a> </font><font face="Verdana" size=2>Manganese violet PV16 is a
very lightfast, semitransparent, lightly staining, dark valued, dull
<a href="http://www.handprint.com/HP/WCL/palette1.html#purple"><b>
purple</a></b> pigment, available from 4 pigment manufacturers worldwide.
The
<a href="http://www.handprint.com/HP/WCL/pigmt6.html#bluetable"><b>
ASTM</a></b> (1999) rates its lightfastness in watercolors as
"excellent" (I) and my 2004 tests agree. In watercolors PV16
undergoes a moderate
<a href="http://www.handprint.com/HP/WCL/cds.html"><b>drying
shift</a></b>, lightening and losing saturation. <br>
</font><font size=3><br>
</font><font face="Verdana" size=2>The PV16 pigment is very consistent
across paint manufacturers. <b>Daniel Smith manganese violet</b> was a
principal source for this pigment: slightly bluer and lighter valued than
other brands, and blossoming more when rewetted. The Winsor & Newton
permanent mauve, previously available only in dry pans, is now (2005)
available in a tube formulation; it has a slightly less saturated, and
darker color that lightens into effective tints and lifts almost
completely to produce cutouts or sculptured edge effects. The MaimeriBlu
mineral violet is more staining and very opaque. Hilary Page noted
discoloration in her sample of Old Holland, which may not have been a
single pigment paint; my swatch began life as a dull, scabby purple, not
at all pleasant to look at, and the vehicle (or pigment?) discolored to a
browish cast after about a month of sunlight exposure. Two thumbs down!
<br>
</font><font size=3><br>
</font><font face="Verdana" size=2>PV16 is the most lightfast balanced
purple pigment available in watercolors, and its recent addition to the
DaVinci and Winsor & Newton is a welcome development. While it has an
assertive and distinctive pigment personality, this becomes less
conspicuous when the paint is part of a shadow mixture. It is attractive
both in full strength and wash applications, but for the most
characteristic color appearance it must be applied with confident, juicy
brushstrokes and left to dry without fussing or retouching. It is
especially good in floral painting, both as a muted floral color and to
add texture and body to browns mixed with deep yellow or orange paints.
The same hue can be mixed from ultramarine blue
(<a href="http://www.handprint.com/HP/WCL/waterb.html#PB29"><b>PB29</a>
</b>) with quinacridone rose
(<a href="http://www.handprint.com/HP/WCL/waterc.html#PV19R"><b>PV19</a>
</b>) or quinacridone violet
(<a href="http://www.handprint.com/HP/WCL/waterc.html#PV19B"><b>PV19</a>
</b>), depending on whether you want more saturation or darker values. In
many respects, PV16 handles like thioindigo violet
(<a href="http://www.handprint.com/HP/WCL/waterc.html#PR88"><b>PR88</a>
</b>) and can play a similar role in landscape or botanical palettes. See
