Orange is my favourite colour to use when designing. The reason I love orange is because it's super friendly, it goes well with other bright colours, it's vibrant and 'colourful' but still warm and pleasing to the eye. It doesn't exclude anyone I feel.
For example: The above identity for a recording studio feels inviting, relaxed, casual, friendly, reliable and fun. However, different connotations occur once I turn the orange into a deep red. (see next post)
