I believe that having good taste is key to be in anything related to creativity, design, communication or the arts. At least for me it is. Now, one thing is to like or dislike certain colors, shoes, furniture style, etc. but that definitely should not be a decision element when creating any type of marketing communication or branding/visual identity system ( logos, brochures, banners, etc) That's what differentiates designing vs creating art. I can talk about both because I do both — When I am drawing or painting because I feel like it I can do whatever I please. If I am drawing or creating illustrations for a client I have to meet the creative brief and deadlines. When I give Creative direction and design for businesses I have to meet the communication/client objectives. For example, if a project calls for loud-bold color palette you cannot go for a white/clean piece just because your house is decorated all white and you like white .... that is a big NO-NO in branding and visual communication. It is important to understand the difference if you want to deliver a clear message that meets the brand or project objectives and purpose.
