RAL Design System plus — hue 070
Unlike 060, this hue has no shades at L\* 20. That is not an omission but a limit of materials technology. Yellow is by definition a light colour: the light reflectance value of a yellow pigment is high, and to make a yellow dark, black or brown has to go in. With that, precisely what makes the yellow yellow disappears. The darkest shade here, 070 30 10 *Mineral brown*, has a light reflectance value of 8.7 and is no longer read as yellow but as brown.
Further round the circle that limit becomes tighter still: 075 and 085 do not even begin until L\* 40. The system shows what can be made opaque with available pigments, not what can be calculated in theory.
The low-saturation shades of this hue lie in the colour of historical ochre paint and of pigmented limewash: 070 50 10 *Saruk grey*, 070 60 10 *Light mahogany*, 070 80 30 *Golden oat coloured*. In restoration and in matching existing plasterwork this is the first area to search, because the earth pigments used there for centuries come out here.

More about hue 070
At saturations above 50 it becomes golden yellow: 070 70 50 *Honeycomb yellow* and, at the outer edge, 070 70 80 *Saffron gold*, the most strongly saturated shade of this hue at C\* 80. That part behaves like a metallic colour without metal — it reads as brass or burnished gold, especially on a glossy surface.
No hue lies closer to the natural colour of European timber than this one. That is at once its strength and its pitfall. A shade lying right next to the colour of oak, elm or larch will not work with it but compete with it: the eye then sees not a colour combination but a failed match, even where the difference is small.
If you are working against timber, choose deliberately: either clearly lighter and less saturated than the timber, or clearly more saturated. The area in between — almost the same colour — is in practice the least restful choice.
In this part of the circle the gloss level carries through more strongly into the perceived colour than in the dark hues. A high-gloss golden yellow reflects the light of the source itself and looks lighter and less saturated; the same yellow in matt reads fuller and darker. With a light reflectance value that rises to 85.2 at the upper end, that difference is large enough to tip a contrast requirement.
So always assess at the final gloss level and on the final substrate, and record the approval on the A4 colour samples as the colour standard.
