Consider using naturally occurring colors when creating your restaurant logo. For example, blue is evocative of the ocean for seafood, and green is a fitting choice for healthy dining. A food logo featuring colors that are too bright, like neon pink or purple, can appear synthetic or even off-putting.
You can also use the principles of color psychology that connect different emotions with different hues for your restaurant branding. For example, red is thought to stimulate the appetite, and yellow is associated with happiness.
