Color of e-Paper

An image is made of pixels. The sizes of every pixel defined who may color are supported by the e-Paper. Monochrome image use one bit for one pixel (0 and 1, black and white), in this case, if we want to display more colors, we should use more bits for every pixel.
You can refer to the Make BMP file for e-Paper" guide and make the image yourself for this module.
We need at least 3bits to display severe color. For easy programming, we and an 0 bit in front of it. In this case, we use 4 bits for every pixel.

Color BIN HEX The color (reference)
Black 0b0000 0x0
White 0b0001 0x1
Green 0b0010 0x2
Blue 0b0011 0x3
Red 0b0100 0x4
Yellow 0b0101 0x5
Orange 0b0110 0x6

For example, if you want to display four colors, green, yellow, red and orange, it should be like as below:

Pixel 1 2 3 4
Bit 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Data 0 0 1 0 0 1 0 1 0 1 0 0 0 1 1 0

Data is saved in MSB formate and 1byte is equal to 8 bits.

Pixel 1 2 3 4
