Hi Anjana, 
After showing a surface, you can either

(A) open an electrostatic potential (ESP) map previously calculated with some other program (DelPhi, Grasp, UHBD, APBS) in Chimera and then use it to color the surface with "Electrostatic Surface Coloring" (in  menu under Tools... Surface/Binding Analysis) or command "scolor"

(B) use the "Coulombic Surface Coloring" tool (in same menu as above) or command "coulombic" to calculate Coulombic ESP and color the surface based on those values

... for example, as in this tutorial:
