Customise color

custom_color(
  feature_vec,
  aes_param = list(color_vec = NULL, date_color_vec = NULL),
  remove_NA = T,
  regexp = NULL
)

`feature_vec`	a vector of factors or characters of the names to plot
`aes_param`	aesthetic parameters. The most important of which is `color_vec`, a named vector for the colors with the names corresponding to those in `feature_vec`. This needs not to be an exhaustive list. Any names in `feature_vec` but not in `color_vec` will be automatically colored.
`remove_NA`	remove NA values from `feature_vec`, i.e., do not color the NA values
`regexp`	which parts of the string in `feature_vec` to remove, in order for it to match `color_vec`. This setting is useful when you try to cope with varying names with the same `color_vec`.
