As an AI language model, I don’t have real-time access to current fashion trends or the ability to predict future fashion trends. The top colors in fashion for the spring/summer season of 2023 have not been determined as of now. Fashion trends can vary greatly from year to year, and it is the result of a combination of factors, including designer collections, industry forecasts, and consumer preferences. It is recommended to refer to fashion magazines, online fashion platforms, or industry experts for the most up-to-date information on color trends for spring/summer 2023.
