Every language has its own way of defining and classifying colours, whose number can vary widely. But every language has got between 2 and 12 terms which are considered 'basic' or 'elementary'.
- English language has 11 : yellow, green, blue, brown, purple, red, pink, orange, black, white, and grey.
- Tanii seems to have 8 : yellow (pilan), green (salyi) grue (jiji), red (lanchan), pink (lamu-layu), orange (pyamin/tormin), white (pulu), black (ji) and grey (mubu).
Different variations or shades of the same colour are distinguished for some of them, especially by means of compound words. Thus
lanchan-lankho for red or vermillon (lit. 'intense, very red'),
lanchan koman for crimson or carmine red (lit. 'dark red'),
salyi koman for dark green,
pilan-pisan for yellowish, etc. Among other words used for expressing shades of yellow colour are
pilan kamo (lit. 'dark yellow', possibly yellow-earth) and
pilan-lanku-lamu (meaning unknown)
Below are displayed the various colours and shades in Tanii according to our present knowledge :

yapun hii jijido => the sky is blue.
anii hii jijido => the leaf is green.
anii hii salyido => the leaf is green.
In this context, both the sky and tree leaves are jiji, although Tanii language does have separate terms for blue and green, jiji and salyi. This is also a typical feature of many East and Southeast Asian languages such as Chinese, Japanese, Korean, Vietnamese, Thai, etc. and, of course languages of the Tani family (Tanii, Adi, Nyishi, Tagin, Miri, Mishing, etc.). Linguists have coined the specific term “grue” (from "blue" and "green"), to describe the range of colours covered by such terms. Thus, jiji would be more accurately referred as "grue" color, not only blue.
Specific colours, or hues, are reserved for animals, such as dorlan (from dor, classifier for quadrupeds and lan, red) which denotes a brown, reddish hue for animal furs, sii talan (apparently a brownish-orange hue for cows), tapu (white, fair color), or tagyo (spotted ?). Human complexions also bear specific names, such as for eg. piikhe for dark complexion. There must be specific colours for certain textiles, dyes, beads... For eg. we don't know the name of this turquoise blue found on some beads which were originally brought from Tibet.
