孟塞爾顏色系統
 | 此條目需要擴充。 (2013年8月1日) |
孟塞爾顏色系統（Munsell Color System）是色度（或比色法）裏透過明度（value）、色相（hue）及彩度（chroma）三個維度來描述顏色的方法。這個顏色描述系統是由美國藝術家阿爾伯特·孟塞爾（Albert H. Munsell，1858－1918）在1898年創製的，在1930年代為USDA採納為泥土研究的官方顏色描述系統。至今仍是比較色法的標準。
早期的幾個色彩體系將顏色放在各種不同的三維色立體，但孟塞爾是第一個把色調、明度和彩度分離成為感知均勻和獨立的尺度，並且是第一個系統地在三維空間中表達顏色的關係[1]。孟塞爾的系統，尤其是其後的再標記法，是基於嚴格的人類受試者測量的視覺反應，使之具有堅實的實驗科學依據。基於人類的視覺感知，孟塞爾的系統熬過了其他現代色彩模式的挑戰，儘管在某些領域其地位已被某些特殊用途的模型取代了，如CIELAB（L*a*b*）和CIECAM02。孟塞爾的系統目前仍然是最廣泛使用的系統[2]。
解說[編輯]
孟塞爾顏色系統的空間大致成一個圓柱形：
色相[編輯]
- 經度=色相（hue）。把一周均分成五5種主色互相調和成五種中間色，相鄰的兩個位置之間再均分10份，共100份。
紅（R）、紅黃（YR）、黃（Y）、黃綠（GY）、綠（G）、綠藍（BG）、藍（B）、藍紫（PB）、紫（P）、紫紅（RP）

明度[編輯]
- 南北上下軸=明度（value）的深淺，從全黑（N0）至全灰（N5）到全白（N10）。
彩度[編輯]
距軸的距離=彩度（chroma），表示顏色的純度。其數值從中間（0）向外隨着顏色的純度增加，沒有理論上的上限（普通的顏色實際上限為10左右，反光、熒光等材料可高達30）。由於人眼對各種顏色的敏感度不同，彩度不一定與每個顏色和明度組合相匹配。
具體顏色的標識形式為：色相 明度/彩度。例如5B 5/10是中等明度（5），高彩度（10）的正藍色（5B）。
| Note that the Munsell Book of Color contains more color samples than this chart for both 5PB and 5Y (particularly bright yellows, up to 5Y 8.5/14), however they are not reproducible in the sRGB color space, which has a limited color gamut designed to match that of televisions and computer displays. Note also that there are no samples for values 0 (pure black) and 10 (pure white), which are theoretical limits not reachable in pigment, and no printed samples of value 1. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
