By the chromosome that leaves a color imprint on the columnar epithelial cell and the neuron will not have that spotted color on it.
No, there are four types of tissue; muscular, epithelial, connective and nervous tissue. Neurons are categorised in the nervous tissue.
Epithelial Tissue- this tissue covers any bodily surface including organs, body cavities, and glands. There are subcategories of Epithelial Tissue, which are Squamous (pavement) , Simple Columnar, Simple Cuboidal, Glandular, Stratified, and Ciliated Columnar. The main functions of epithelial tissue are sensation, absorption, protection, cleaning, reduction of friction, excretion, diffusion, and secretion. Connective Tissue- this tissue forms blood, cartilage, and bone. It is classified into dense connective, loose connective, reticular, elastic, and adipose. Muscle- contractile tissue that causes movement in an organism as well as internal functions. The three types of muscle tissue are skeletal, smooth, and cardiac. Nervous Tissue- this tissue is responsible for sending and receiving messages from muscle tissue to the brain. Nervous tissue is composed of neurons.
Interneurons or association neurons.

Interneurons or association neurons are connector neurons that establish connections between other neurons.
Motor neurons are the neurons that conduct impulses from the central nervous system to cardiac muscle, smooth muscle, and glandular epithelial tissue. These types of nerves are what make up the Autonomic nervous system, which regulates the bodies involuntary functions.
Interneurons are the neurons that make up the central nervous system (the brain and spinal cord). They internally communicate between the input from sensory neurons and our physical reaction triggered by the motor neurons.
The SYNAPSE is the very small space between two neurons and is an important site where communication between neurons occurs.

A Synapse is the space between two neurons or between a neuron and a receptor organ. A single neuron can have a few, or several hundred synapses.
Contact between neurons, as you put it, is achieved through electrical impulses towards and from your brain.
