Brands and businesses have logos of different colours. While there is a science to picking brand colours and shop/window colours, brand owners pick colours for different reasons. These range from selecting their favourite colours to more intentional reasons like the practicality of the colour they pick. An example of the practicality of a colour would be if you had a water brand, the typical default colour would be blue.
In marketing and branding, we use colour psychology to shape consumers' perceptions and influence their emotions with regard to the goods and services being provided by the brand owner. The choice of colour imparts perceived meaning and gives personality to the brand.
While the individual colours impart these emotions, pairing colours may have different effects. Make sure you have good contrast without clashing colours. At the end of the day, a sloppy logo, in spite of an intentionally selected hue, will still be a sloppy logo.
