Maimeri - Polycolors

by Zsolt

Polycolors are created by Maimeri. Polycolor contains a special ultra fine acrylic emulsion binder, a high tech product which dries to produce an extremely strong, resistant, supple, opaque film which performs very well even outdoors, exposed to natural elements.

The measurement files are in cxf format and can be used by Eye-one Share (GretagMacbeth production).

 

Primary and acromatic colors:

 Number  Name  Pigments  Transparency
 018  Titanium White  Titanium Dioxide PW6  Opaque
 116  Primary Yellow  Hansa yellow G PY1, Titanium Dioxide PW6, Hansa Yellow 10G PY3  Opaque
 256  Primary Red - Magenta  Quinacridone PR112, Thioindigoid PR88  Opaque
 400  Primary Blue - Cyan  Titanium Dioxide PW6, Phthalocyanine Beta PB15:3, Chlorinated phthalocyanine PG7  Opaque
 530  Black  Synthetic Iron Oxide PBk11, Carbon Black PBk7  Opaque

 

 

Maximum saturation:

The paint bases usually do not have maximum saturation "out of the tube" in spite of what people often think. They need to be mixed to white (018-Titanium White) to reach full chroma (saturation). The only exceptions are yellows in my experience. The following images show the computed trajectories of color (black lines) when the primaries are mixed to white (on the left) or to black (on the right), starting with the pure paint base and ending with white/black. The light grey lines mark the boundary of a monitor gamut with WP at 6500K. The color spaces are in the following order: CIE ab plane, xy plane and Munsel HS plane. The small circles on the trajectories show the maximum chroma computed in the CIE-Lab space.

The following table shows how many parts out of 100 parts of mixture, having maximum chroma in the CIE-Lab space, are color (and the remaining parts are of white of course). The XYZ color coordinates are also reported for the maximum color saturation.

Mixing 50% grey:

Mixing 50% colored gray with D65 illuminant needs the following recipe: 018:7 + 116:4 + 256:6 + 400:3

Here are the trajectories in the 3 color spaces leading to the 50% grey, with trajectories shown between each primary pair (these lines mark the boundaries of the 116+256+400 paint color gamut too):
