RAL Design System plus — hue 060
At saturations 05 and 10 this hue yields colours which in practice are given not a colour name but a category: 060 60 05 *Screed grey*, 060 80 10 *Soft greige*, 060 40 10 *Moor oak grey*. They are greys with a minute warm direction, and that is exactly why they are usable where a pure grey turns out too hard.
That is bound up with simultaneous contrast. A neutral grey next to warm timber or next to a yellow brick looks cool and often greenish; a grey from this hue compensates for that difference and only then really reads as neutral. Anyone looking for a neutral impression in warm surroundings ends up here more often than on the grey axis.
In this hue the saturation runs up to C\* 80, with 060 60 80 *Accent orange* at the outer edge. In this case the name is an instruction for use: this is a colour for a limited surface in an otherwise muted palette — a push button, a handrail, a machine part that the hand has to find.

More about hue 060
Between those two extremes lies the middle area with shades such as 060 60 60 *Bitter orange* and 060 70 30 *Peach yellow*. There the hue is usable on larger surfaces, because the saturation stays low enough not to keep tugging at the attention.
Yellow-orange is sensitive to the light source. Under warm artificial light this hue gains saturation and moves towards orange; under cool light it loses warmth and the low-saturation shades tip towards grey. The difference is greatest with precisely those greige tints where the colour direction is minimal to begin with: a choice that is right under workshop light can turn out neutral grey or visibly beige in the final situation.
Two shades that look the same under one light source and not under another — metamerism — moreover occur more often in this area than in saturated hues, because there are several pigment combinations that give the same weak effect. So assess under the light of the final situation.
The range runs from L\* 20 to L\* 93, with light reflectance values from 6.2 to 84.7. The darkest shade, 060 20 05 *Industrial black*, is a brown-black; the lightest, 060 93 05 *Wool white*, an off-white. Within that spread, lightness determines the perceived weight of a surface: dark weighs, light recedes. That works here almost as purely as on the grey axis, because at the lowest blocks the saturation hardly plays a part.
With the near-neutral shades of this hue in particular, the difference between two neighbouring positions is small — too small for a screen and too small for a fan-deck sample on a large wall. Choose with the fan deck or the colour book and approve on the A4 colour samples as the colour standard, next to the material the colour will sit against.
