Gamers really could use to wash more (see what I did there?).
From the review:
Today we take a look at the lovely acrylic wash series by Secret Weapon miniatures which I have had the pleasure of thoroughly testing out. The range consists of 30 different shades, and most of them are not your regular shades of washes. Most wash ranges deal in a select few shades that are the most basic washes that essentially will work for shading any colour lighter than itself. The SWM washes however, offers a wider variety of shades as well as some really interesting ones that I haven’t seen in any other ranges.
