I feel , its the more divisons in green color zone but purpose is same .

The leaf colour chart (LCC) was the first time introduced in the agricultural sector of the world by scientists of Japan. Theymade it for estimation of chlorophyll formation and its availability in plants, after the continuous studies, many researchers proved that it is pivotal for the measurement of nitrogen deficiency and its correction. It is easy to use (Nachimuthu et al., 2007). The leaf colour chart has six (06) colours varies from yellowish to dark greenish just like lush green colour of plants, each colour is changed from the one another. Sathiya et al., 2009) and has size about three multiply by eight (3x8) which is constructe d of good quality plastic material (Singh et al., 2006). However, In different regions of Asia the

leaf colour chart used is seven centimeter (07 cm) wider and

about thirteenth to twenty centimetres (13 to 20 cm) longer,

contains 4 to 6 colours, starts from yellow and ends with lush

green at last (Hushmandfar & Kimaro, 2011). A researcher

belongs to Zheijiang Agriculture University, China produced

leaf colour chart comprised 8 colours (Yang et al., 2003). Similar

work was already conducted at University of California researcher added all eight colours with green colour by some changes. While, a IRRI scientist prepared LCC in which have only 4 colours (Boyd, 2001; Fairhurst et al., 2007).
