Why does ggplot (.predict) not change color/palette in R?

问题

Please find My Data below. I have the following plot

I want to apply the "jco"-palette (or just manually typing a "#xxxxxx"-color). However, I cant make it work. I have tried

library(ggplot2)
library(ggsci)
ggplot(Predict(model, ref.zero = TRUE, fun=exp)) + scale_color_jco() + scale_fill_jco()

How can I

1) Manually change the color to #xxxxxx?

2) Apply the JCO-palette?
