RAL Design System plus — hue 095
In the yellow-green part of colour space, perceptible colour differences lie close together. Two colours ten degrees apart in hue angle read as virtually the same colour in the blues and as two clearly different ones in this area. With an average hue angle of 96 degrees, 095 sits exactly in that narrow region. Without this hue the jump from yellow to yellow-green would feel larger than any other jump in the circle.
In practice that yields a finer control. If a yellow has to become slightly less yellow without already being green, 095 is the answer where 100 would go too far.
The range is 42 shades and does not begin until L\* 40. Below that there is nothing: the darkest shade is 095 40 20 (Forest green) with an LRV of 13.9. In saturation too the hue stops at 80 instead of the 90 of 090. Both limits have the same cause — in this area, colours that are very dark and saturated at the same time cannot be made opaque with the available pigments. The system shows what is reproducible.

More about hue 095
So anyone needing a dark colour here turns to 100, which does run down to L\* 20. That is a shift in hue of half a step and is barely noticeable in use; the alternative — forcing a dark shade that does not exist — costs more.
The official names in this hue are strikingly unanimous: 095 50 40 (Garden lettuce green), 095 60 50 (Gooseberry green), 095 70 40 (Banana green), 095 80 30 (Asparagus yellow). That is no accident of the naming but an indication of how the area is read. Yellow-green is the colour of young foliage and of unprocessed food, and that association is strong enough to give the colour a meaning of its own.
In retail and hospitality that is worked with deliberately: where freshness is the theme, this is the area people look in. Outside that context the same association works against you — in an office setting or a technical application, yellow-green is read as unintended rather than as chosen.
A colour from 095 carries two directions within it, and that makes it harder to place in a palette than a pure yellow or a pure green. Next to a warm neighbour it reads green, next to a cool neighbour yellow. Put it beside timber and you see the yellow side come forward; beside concrete or galvanised steel the green side instead.
The solution lies not in the colour but in the saturation. The weakly saturated shades, up to about C\* 20, are stable enough to keep the same impression in changing surroundings. From C\* 40 upwards the colour goes along with its neighbours and the palette around it has to be fixed, not just the colour itself.
Precisely because this hue is a half step, the difference from 090 and 100 is barely visible on a screen. Compare the three side by side on the fan deck or in the colour book while you are choosing, and for approval lay the A4 colour samples next to the material the colour will sit against.
