Popular colours in online casinos and their effects

When you play a game at an online casino, you notice a few colours popping up, these include red, black, blue, green, gold and yellow. These colours aren’t picked at random. In fact, there is a lot of theory that goes behind these colours, below we look more into this. 

Red - Excitement, urgency and passion

When you load up an online casino, you will notice a lot of games use red as a dominant colour - roulette instantly springs to mind. The reason this is used is that red is exciting and promotes urgency. Red often highlights high-reward features, encouraging players to take risks. It also increases heart rate and adrenaline, making gameplay feel more thrilling.

Green – Wealth, luck, and relaxation

When you think of green, what instantly springs to mind? For a lot of people, the answer is money. Many online roulette tables use green felt, a tradition dating back to physical casinos. Online platforms often use green felt to signal luck and wealth, and it is the colour that has universally been linked to money, thanks to it being the colour of notes. When on an online casino platform, they use green to signal bonuses, free spins and more, reinforcing the idea of financial gain. Therefore, it’s a really positive colour to use and can psychologically make people think they are going to win and want to spend even more. 

Black – Elegance and mystery 

We mentioned the red that roulette uses above. Now think about the other dominant colour that is used, and that is black. Black is often referred to as a sophisticated colour and is used in a number of ways in different online casino games. By using black, it creates a sleek, luxurious finish, which is professional. It also adds an air of mystery, which makes the games feel more intriguing. 

Gold/Yellow – Luxury, optimism, and high rewards

It will come as no surprise that gold is a very popular colour to use. Gold is a powerful symbol which represents wealth, success, luxury and high levels of money. The aim of playing online casinos is to enjoy yourself and hopefully make more money than you put in (you should always bet responsibly). By using gold within their colour scheme, it gives off the idea that you can be rich by playing and that you have the chance of coming into a lot of money. 

Blue: Trust and Stability

A popular colour that is used by a lot of online casinos is blue. Blue is favoured as it has a connotation of being calming, relaxing and trustworthy. Many reputable online casinos use blue to appear secure and professional, and a place that you can trust - this is very important, as you will be depositing your money with them. The calming effect of blue is used to try and prevent players from feeling overwhelmed when placing their bets - the calming sensation can also help during long gaming sessions. Slots are a good example, where a lot will base their game around being in the water; this way, they can play off the blue colours of the ocean.
