DESIGN PHILOSOPHY

This logo is very contemporary in design.It is based on the theme of convergence.The different swatches of colours represent the different concentrations,coming together in a beautiful convergence,giving rise to a remarkable scene lifted from nature.Convergence by meaning is,"To come together from different directions."

This logo epitomizes GPCET to be the icon of knowledge,and communicates the institution's pioneering vision of a beautiful convergence of innovation and education in its different concentrations.
Colour in the logo is mainly the synchronisation and convergence representing various concentrations individually and merging together as a knowledge bank.The GPCET. The tag line reinforces the vision-'Pioneering Innovative Education'.

DESCRIPTION OF COLOURS
