The Munsell Color Tree
Colors everywhere, but who can count them all?!

Historical Problems with Identifying Colors
• Theoretical Problems– Numerous color concepts– Different theorists organize properties of
color into different functional systems• Leonardo da Vinci (15th Century)• Newton – discovered spectrum and devised color
circle • J.C. Le Blon – observed primary nature of red,
yellow, blue and described hues from mixing (1756)• Moses Harris – published first color circle in full
color (1766)
Different Color Wheels
• Color wheel 1
Historical Problems with Identifying Colors
• Practical Problems– Individual color
vocabulary• Breadth• Definitions/
associations
– Trade names and commercial naming
• Behr Paints
Various Color Classifications
Munsell Solves Color Problems!
• Albert H. Munsell– Seascape painter of the 1890s– Munsell System of Color Notation
(1905)– One of the color standards used by
the US National Bureau of Standards– Used in science, industry, and art
• Soil samples
What is the Munsell Color Tree?
• 3D Spherical Model• Incorporates
concepts of hue, value, and chroma in one model
• Organized in a numerical classification system
• Inclusive of all colors – each color has its own place
How does it work?
• Based on the 2D Color Wheel– Includes primary,
secondary colors, i.e. hues– Can be expanded to
include intermediary hues
• Shows all variations of colors/hues, which are at full intensity on the wheel
• Notation: 5.0 + letter5.0 R = red5.0 BG = blue
green
How does it work?• Value Scale
– The lightness/darkness of a particular hue
– Related to brightness, luminosity– Vertical arrangement: the “trunk”
of the color tree
• Nine levels of values– 1 = black– 9 = white– Notation: 5.0 R 5/ ; 5.0 BG 7/
• Values of hues are compared with this neutral gray pole
How does it work?
• Chroma– Refers to
strength/weakness of a hue at a certain value
– Related to purity, saturation, intensity
– Horizontal arrangement: the branches of the tree
• Fourteen levels of chromas– 1 = dullest, most gray
variation of the hue– 14 = most intense,
pure state of the hue– Notation: 5.0 R 5/6;
5.0 BG 7/8 (even numbers)
– 5.0 R 5/12 is redder than 5.0 R 5/10
Value and Chroma
To sum up…• Hue – purest form of a color
– 5.0 R; 10.0 YRY– Leaves of the tree
To sum up…• Hue – purest form of a color
– 5.0 R; 10.0 YRY– Leaves of the tree
• Value – placement along the gray scale– vertical axis (trunk)– 5.0 R 5/
To sum up…• Hue – purest form of a color
– 5.0 R; 10.0 YRY– Leaves of the tree
• Value – placement along the gray scale– vertical axis (trunk)– 5.0 R 5/
• Chroma – intensity of a hue– horizontal axis (branches)– 5.0 R 5/14 (most intense red)
To sum up…• Hue – purest form of a color
– 5.0 R; 10.0 YRY– Leaves of the tree
• Value – placement along the gray scale– vertical axis (trunk)– 5.0 R 5/
• Chroma – intensity of a hue– horizontal axis (branches)– 5.0 R 5/14 (most intense red) Each hue has
it’s own page on the tree
• Each hue chart also has different # of chips depending on the chroma possibilities of each hue at value levels
Making our Munsell Color Tree
Obstacles
• Sorting through vast pool of color chips ~1500 at Home Depot (we got lost getting there, too)
• Taunts from the Home Depot Staff• Eyestrain and bodily fatigue from
constant visual comparisons and matching, and fluorescent lighting
• Limited spectrum of Behr color palette – Resulted in several empty slots
Making our Munsell Color Tree
Choices• Construction/Display of our Color Tree
– Wanted: 3-dimensional, rotating pages, upright
• Black background to emphasize color contrasts
• Shortened chroma range on each page– Eliminated 1 – gray tone– Eliminated 14 – most hues do not reach
this intensity, only red
