Acrysion - oranžově žlutá

A warm yellow with an orange cast

The shade stands exactly on the border of yellow and orange – where the paints meant to be seen sit. Modelers reach for it for the warning areas of trainer aircraft, for rescue and fire service hardware, for signal stripes on rotors, for working machines and for the brackets and bumpers of construction equipment. It also serves well on road signs and on accessories for scenes where the eye is meant to catch a color signal at once.

Yellow and orange pigments are among the worst covering ones of all. Straight onto dark plastic it takes five passes or more without exaggeration and the result is still dirty. The way out is simple: a white or light gray base first, and only then two to three thin coats of this tone. That raises not only the strength of the color but also its stability under later weathering.

Thinning and airbrush maintenance

It is thinned with water; the thinner from the same line gives a finer mist. Once the work is done it is worth flushing the airbrush right away, because pigment residue stays in the nozzle and clings tenaciously once dry. Dried deposits on the needle and in the cup come off with the cleaner made for this line. The bottle has to be stirred before every draw, otherwise the shade comes out slightly different every time.

Small things that decide the result

Warning areas on real machines tend to be bounded by a sharp line, so it pays to mask only once the paint underneath has cured completely – a fresh acrylic film likes to peel away with the tape. Signal paintwork also fades and gets dirty quickly on machines in service, so it is worth evening it out gently with a thin dirty glaze once dry.
