RAL Design System plus — hue 010
Here lies a distinction that is often confused in practice. Within the red hues 010 is the coolest: beside 030 it reads unmistakably bluer. But on the warm–cool scale of the colour system as a whole, 010 is still pronouncedly warm. The maximum of colour warmth lies at a hue angle of around 50 degrees, in the oranges; 010 is close enough to it for the warmth to remain dominant.
What makes the red restrained here is therefore not coolness but distance from orange. And that distance translates into use: a tone from 010 looks controlled where the same lightness level in 040 immediately demands attention. That explains why this hue recurs in hospitality, retail and corporate applications where red has to speak without shouting.
Red is the colour that is noticed fastest and stays recognisable longest as the visual system declines. In care settings that is well known: where other colours merge into one another with age and dementia, red keeps standing apart. For landmarks and wayfinding that is a property worth using deliberately.

The flip side is that red is hard to ignore. On a large surface a saturated shade from this hue keeps demanding attention, even when that attention is unwanted. The muted shades at the left-hand end of the saturation scale are therefore far more usable in interiors than the saturated ones.
55 shades, from L\* 20 to L\* 93 and from C\* 05 to C\* 53. The darkest positions read as burgundy, the lightest as muted pink; between them lies the whole field you need to build a layered colour scheme within a single hue.
Most shades sit around L\* 40 and 50 — that is where red can be saturated most strongly. Towards the light side the range narrows quickly: at L\* 93 only one remains.
Red is the hardest colour family to apply evenly. Red pigments cover less well than neutral ones, so film thickness has a stronger effect on the final result. Two batches with the same code can differ visibly when they have been sprayed differently or built up differently. For approval, therefore, use the A4 colour samples as the colour standard, not a fan deck sample.
