Spectrum abstracts

I've just finished these two abstract acrylic paintings, each 7 x 7 inches, based on the gorgeous colours of minerals viewed through a petrological microscope. The pure colours of these crystals are very beguiling, and as you rotate the microscope stage, the colours change through the spectrum. The roughly painted black fracture lines give the effect of a stained glass window. These two paintings can be seen at http://www.etsy.com/listing/78977572/spectrum-abstract-1-original-acrylic and http://www.etsy.com/listing/78977825/spectrum-abstract-2-original-acrylic
