Well the previous answers give you the definition... Here is some etymology for you to understand it better.

Chromophore from the Greek "Chroma"=colour and the verb "Phero"=to bear, carry. Thus a group which is responsible for the colour of a compound is called a chromophore (colour-bearing group)

Chromogen from the Greek "Chroma"=colour and the verb "genno"=give birth to, produce.
Substances which can be converted into pigments or dyes (can produce coloured groups) are called chromogens

Chromophore:
===========

A chromophore is the part (or moiety) of a molecule responsible for its color.

When a molecule absorbs certain wavelengths of visible light and transmits or reflects others, the molecule has a color. A chromophore is a region in a molecule where the energy difference between two different molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromophore can thus be absorbed by exciting an electron from its ground state into an excited state.


Chromogen
=========
It's a substance capable of conversion into a pigment or dye.

chromophore - molecule that is detected spectroscopically

chromogen - parent molecule of dye

i do assays with AChE and DTNB so DTNB anion is the chromophore, and the chromogen is DTNB
