How to change outliers to some other colors in a scatter plot

Question

If I have a scatter plot like this

I was wondering is there any way to change the obvious outliers, like the three on the top, to some other colors in the same plot?

ImportanceOfBeingErnest has a great answer. Here's a one-liner I use if I have an array corresponding to enum categories for the data points (especially useful when visualizing data pre divided into classes).

import numpy as np
import matplotlib.pyplot as plt

num = 1000
x= np.random.rand(1,100)
y= np.random.rand(1,100)*2

# Creating a simple data point classification criteria, classes in this case will be 0, 1 and 2
classes = np.round(y)

# Passing in the classes for the "c" argument is super convinient
plt.scatter(x,y, c=classes,cmap=plt.cm.Set1)
plt.show()

Corresponding scatter plot that divides the graph into 3 colored regions:
