How to change scatter colors in plotly express?

Hi,
is there any way to change default scatter colors in this code?

import plotly.express as px
iris = px.data.iris()
fig = px.scatter_matrix(iris,
    dimensions=["sepal_width", "sepal_length", "petal_width", "petal_length"],
    color="species")
fig.show()

I’d like to change default color blue and red to green and orange; orange for species X, green for species Y
If you could help.
Thanks

That’s a question for #api:python
