:info: † - the "taupe" colour (also known as clear) is the colour used to reset the display to a default, clear state. We misuse this as an extra colour on 4.0" and 5.7", but the 7.3" display clear colour is a sort of muddy, greenish gradient that's not consistent enough. You can stil use it, by all means, but it wont be considered for dithering.
You can use colours outside of these eight by using `create_pen(r, g, b)` or `create_pen_hsv(h, s, v)`.
These colours are available as constants in the `inky_frame` module so you don't have to remember which number corresponds to which, eg:
```python
display.set_pen(inky_frame.YELLOW)
```
You can use colours outside of these eight by using `create_pen(r, g, b)` or `create_pen_hsv(h, s, v)`. eg:
```python
my_colour = display.create_pen(255, 128, 0)
display.set_pen(my_colour)
```
PicoGraphics will do its best to match your colour choice by mixing the available colours with a dither pattern. This works best on large areas of colour such as backgrounds, big UI elements or chunky text. See the `inky_frame_dithering.py` example for a demonstration.
:info: Due to the lack of light blue or pink native colours, Inky Frame isn't very good at reproducing pink, purple, violet or light blue, cyan and teal.
