The entire center of her dress has undershot the blackpoint and is washed out entirely in black, and the representation of the headdress is extremely high variance. These are similar problems to people what people face attempting to print out digital photos or artwork without properly managed color.&lt;p&gt;At a minimum you would want to adjust the color gamut of the image by hand to line up with the lego color gamut so the end result is more pleasing, more concretely that means spending some time on the hue&amp;#x2F;saturation&amp;#x2F;lightness&amp;#x2F;color curve filters until those conversion artifacts are minimized. A more theoretically interesting way to do it would be to use a gamut matching algorithm with a discrete color space defined by the available lego bricks.&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.colourphil.co.uk&amp;#x2F;rendering_intents.shtml&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.colourphil.co.uk&amp;#x2F;rendering_intents.shtml&lt;/a&gt;

But the optimization of the different sized pieces also seems like a very fun problem to work on!&lt;p&gt;And taking the step to actually getting out of the digital world is something everybody should probably do more often!</text></comment>
