 Another use is to set colours, under the `[colors]`. The following labels are customizable with hex colour code strings:
 
-- Table header colours (`table_header_color="#ffffff"`).
-- Every CPU core colour as an array (`cpu_core_colors=["#ffffff", "#000000", "#111111"]`).
-  - bottom will look at 216 (let's be realistic here) colours at most, and in order.
-  - If not enough colours are provided for the number of threads on the CPU, then the rest will be automatically generated.
-- RAM and SWAP colours (`ram_color="#ffffff"`, `swap_color="#111111"`).
-- RX and TX colours (`rx_color="#ffffff"`, `tx_color="#111111"`).
-- Widget title colour (`widget_title_color="#ffffff"`).
-- General widget border colour (`border_color="#ffffff"`).
-- Current widget border colour (`highlighted_border_color="#ffffff"`).
-- Text colour (`text_color="#ffffff"`).
-- Label and graph colour (`graph_color="#ffffff"`).
-- Cursor colour (`cursor_color="#ffffff"`).
-- Current selected scroll entry colour (`scroll_entry_text_color="#282828"`, `scroll_entry_bg_color="#458588"`).
