Grey is a neutral color that can range from very light to very dark. There are many different shades of grey, each with their own unique shade code used for design, manufacturing, and identification purposes. When referring to dark grey specifically, this typically encompasses the darker end of the grey spectrum, from medium grey all the way to near-black charcoal shades. Determining the exact shade code for dark grey depends on how dark you want the color to be and what coding system you are using.
Grey Color Systems
There are a few main color systems that are commonly used to specify shades of grey:
The Pantone Matching System (PMS)
Pantone is a standardized color matching system used in design, printing, and manufacturing. Within the Pantone system, grey shades are coded with numbers ranging from PMS 401 to PMS 419, with 401 being the lightest grey and 419 being pure black. The darkest grey shades in the Pantone system are:
- PMS 418 C: Charcoal grey
- PMS 419 C: Black
PMS 418 C is the darkest true grey shade before black in the Pantone system. It represents a very deep charcoal grey color.
CMYK Codes
CMYK stands for cyan, magenta, yellow, and key (black). It is a color model used for printing. CMYK codes specify the percentages of each ink used to produce a given color. For grey shades, the percentages of cyan, magenta, and yellow are all equal, while only the black (K) percentage varies. Darker greys have higher black percentages. Some common CMYK codes for dark grey are:
- C:0 M:0 Y:0 K:75 – Dark charcoal grey
- C:0 M:0 Y:0 K:90 – Very dark grey just before black
As you get closer to a black shade, the K value approaches 100%.
RGB Codes
RGB stands for red, green, and blue – the three primary colors used in light to produce other colors. RGB codes are commonly used for digital and on-screen applications. In RGB codes, grey colors are produced by equal values of R, G, and B. Here are some sample RGB codes for dark greys:
- R:105 G:105 B:105 – Dark medium grey
- R:55 G:55 B:55 – Charcoal grey
- R:35 G:35 B:35 – Very dark charcoal
Lower equal values of R, G, and B produce darker shades of grey.
HEX Codes
HEX codes are 6-digit codes prefixed with a hashtag (#) that define colors for digital design. HEX codes are derived from RGB values. Some dark grey HEX codes are:
- #696969 – Dim grey
- #2F4F4F – Dark slate grey
- #333333 – Very dark grey, near black
In general, HEX codes starting with lower numbers produce darker grey shades.
Shade Names for Dark Greys
In addition to the various color codes, dark grey shades also have descriptive shade names to help identify them:
| Shade Name | Characteristics |
|---|---|
| Charcoal | Very dark grey with black undertones, akin to the color of charred wood |
| Slate Grey | Dark grey with blue/purple undertones |
| Onyx | Extremely dark grey, nearing black |
| Smoke | Dark grey with black and white mixed in, giving a smokey appearance |
| Iron | Dark grey reminiscent of cast iron |
| Pewter | Dark grey with hints of blue, similar to the metal alloy pewter |

These names can help give an indication of the tone and visual character of specific dark grey shades.
