[R] Change colour ggiNEXT plot package iNEXT

[Luigi Marongiu]

Dear all,
is it possible to provide custom color to the rarefaction curve of the
package iNEXT (ggiNEXT)?
If I have these data:
```
library(iNEXT)
library(ggplot2)
data(spider)
out <- iNEXT(spider, q=0, datatype="abundance")
ggiNEXT(out, type=1)
```
can i colour the lines with, let's say, yellow and green?
Thank you
