How do neon signs get their colour?
As you will already know neon signs come in a wide array of different colours. This helps them to stand out and can reflect specific brands. What you may not know is how the sign maker achieves the different colouring. It is very interesting and showcases why many people view their creation as a form of art. As one of the leading neon sign manufacturers in the UK, we are proud to share this information.
All neon signs contain gases. When an electrical current is introduced it disturbs the atoms, causing them to deviate from their orbit. The free electrons then collide with each other before being absorbed back into their rightful place. This produces light.
Traditionally all of the signs were filled with neon gas. When the current flows through, disturbing the atoms, it creates a red light. Switching to a different gas changes the colour. For example helium produces orange, mercury vapour creates light blue, and argon is lavender. The gases can even be mixed together to create different shades.
Another way that the signs can get their colour is by baking fluorescent powders inside the glass tubes or by using different coloured glasses to create the tubing. Both can work effectively, achieving the right colours.
A final option is to create the sign in sections, keeping them separated from one another. By doing this each can be unique, featuring a specific gas or mix of them. The combination of sections will create the look you want.
