Intrinsic Designs
Four articles on the part of interior work decided by eye and regretted at invoice stage: undertones, orientation, material pairing and palette proportion. Every colour named on Intrinsic Designs is given as a hex value with a light reflectance value computed from that hex.
Scope
Intrinsic Designs runs four articles covering 20 reference colours between LRV 98 and LRV 3. Paint undertones handles near whites, north facing room colour handles orientation and daylight temperature, pairing stone and timber handles value contrast, and building a material palette handles proportion measured in square metres.
| Article | Palette range | LRV range | Threshold the article turns on |
|---|---|---|---|
| Paint undertones | #FFFDF8 to #F1EAE7 | 98 to 83 | A2 board at 2,495 sq cm, 100 times a 50 mm chip |
| North facing room colour | #DDE1DC to #5B6668 | 74 to 13 | LRV 65 ceiling for cool greys under 7500K light |
| Pairing stone and timber | #E8E4DB to #3A3A38 | 78 to 4 | 25 LRV point minimum gap within one hue family |
| Building a material palette | #F0EDE6 to #2C2C2A | 85 to 3 | 60 30 10 measured across 104.7 sq m of surface |

Undertones
Five near whites run from #FFFDF8 at LRV 98 down to #F1EAE7 at LRV 83, a spread of 15 points that hides four separate tints. A matt white card exposes the undertone at the join within two seconds, and a 50 mm fan deck chip covers one hundredth of an A2 sample board.
Light
North light holds near 7500K from 09:00 to 16:00 and never turns warm, so a cool grey above LRV 65 returns bare concrete on a north facing wall. One green grey family runs from #DDE1DC at LRV 74 to #5B6668 at LRV 13, and the darker members gain.
Materials
Limestone #E8E4DB sits at LRV 78, travertine #BFB6A6 at 47, oak #8A6A45 at 16, walnut #5C4327 at 6 and basalt #3A3A38 at 4. Two materials in the same hue family need a gap of 25 LRV points or more, and sealing a stone closes that gap by up to 10 points.
Palettes
A five colour palette covers a whole house: #F0EDE6 at LRV 85 as field, #CBC6BA at 57 as secondary, #7C8C7F at 25 and #B4623B at 19 as accents, #2C2C2A at 3 as ink. In a 4 m by 5 m sitting room the 60 30 10 split works out at 62.5, 31.3 and 10.9 square metres.
