Colour Technical Profile

LRV

24.5

Hue

149°

Saturation

Lightness

24%

In HSL coordinates, Charcoal sits at hue 149°, saturation 2%, and lightness 24%. That places it among the neutral tones with very low saturation, close to the RAL reference . US exterior lines such as Sherwin-Williams Duration, Benjamin Moore Aura Exterior, Behr Marquee carry close matches across their 100% acrylic and elastomeric ranges; ask your paint store for a computer-tinted match to the #3D3F3E HEX value.

The Light Reflectance Value (LRV) calculates to 24.5 using the WCAG relative-luminance formula (0.2126·R + 0.7152·G + 0.0722·B). LRV drives two practical outcomes for any exterior: how much solar heat the walls absorb, and whether the colour is compatible with exterior insulation finish systems (EIFS in the US, external wall insulation in the UK). At LRV 24.5 you are in the safe range for most cladding and EIFS assemblies, but still absorbing enough solar load that UV-stable pigments and a quality 100% acrylic binder are essential to prevent premature chalking.

The mathematical complement (180° across the hue wheel) lands on a desaturated magenta - best reserved for a small accent such as a door or mailbox rather than the main field. The existing accent of Walnut Wood (#5A3A22) sits at a controlled contrast ratio that grounds the composition without breaking it up.

Where This Combination Works Best

Architectural Match

The Mid-Century Modern style is tailored to the following home types: Mid-Century Modern, post-and-beam, Palm Springs. On contemporary and transitional suburban homes this combination stays current without locking the house into a single aesthetic era.

Climate & Orientation

With an LRV of 24.5, this is a dark exterior colour. On south- and west-facing elevations surface temperatures can exceed 160°F, which most EIFS and some vinyl-siding warranties explicitly exclude. Reserve for north and east exposures, or specify infrared-reflective (IR) paint technology (such as Sherwin-Williams SunBlock or Benjamin Moore Element Guard) to cut absorbed heat and prevent substrate damage.

Urban & Regulatory Context

Before painting, check your HOA covenants - an estimated 60% of new US homes are governed by HOA rules, and many require Architectural Review Board (ARB) approval for exterior colour changes, with approved palettes limited to 15-30 pre-selected swatches. In designated historic districts, a Certificate of Appropriateness from the local preservation commission is often required in addition. This mid-century modern palette is broadly consistent with neighbourhood-friendly suburban expectations, but always submit paint chips and a written description to your HOA before ordering materials - retroactive enforcement can require repainting at the homeowner's expense.
