 ## Description
 
-**<mark>COLOR</mark>** is a unit can detecte the color of object surface which integrates **TCS3472** (a color sensor). The unit comunicates with M5Core with I2C.
+**<mark>COLOR</mark>** is color recognition unit with integrated **TCS3472** chip.
+
+**Identify color principle:**
+
+In the TCS3472, a 3*4 array of filtered photodiodes and a analog-to-digital converters are embedded. Of the 16 photodiodes, 3 have red filters, 3 have green filters, 3 have blue filters and 3 have no filter(clear).
+
+<img src="assets/img/product_pics/unit/color/unit_color_07.png">
+
+When detecting the color of an object, TCS3472 returns data from four channels: red(R), green(G), blue(B) and clear(C)(non-filtered). The response from the red, green and blue channels (RGB) can be used to determine a particular source’s chromaticity coordinates (x, y).

+
+**识别颜色原理：**
+
+在 TCS3472 中，内嵌了 3*4 阵列的滤波光电二极管和 16 位模拟转转换器。在 12 个光电二极管中，3个具有红色滤光片，3个具有绿色滤光片，3个具有蓝色滤光片，3个没有滤光片（透明）。

+
+
+检测物体颜色时，TCS3472 会返回四个通道数据 - 红色（R），绿色（G），蓝色（B）和清除（C）（未过滤）。红色，绿色和蓝色通道（RGB）的响应可用于确定特定光源的色度坐标（x，y）。
