Question: I'm looking for a solution that helps designers and marketers find pleasing color combinations quickly and easily.

If you're looking for a tool to help designers and marketers find good color combinations, Khroma is a top contender. This color tool uses AI to create custom palettes based on your preferences, with an algorithm trained with a neural network. It has features like personalized color generation, an infinite number of palettes, search and filtering, and a collection system to organize your favorite palettes.

Another good option is Huemint, a machine learning-based color palette generator. It has a variety of generation options, including custom color schemes for brands, websites and graphics. You can choose from different AI models and adjust contrast settings, and the tool can also accept image uploads to generate palettes. Huemint's variety of presets and generation options make it a good utility for improving your visual identity.

If you're looking for a more full-featured editing tool, Radiant has advanced photo editing abilities including color grading and automated editing processes. It's a photo editing tool, but its color manipulation abilities can be useful for designers trying to improve their palettes. With native plugins for Adobe Photoshop and Lightroom, it fits in well with existing workflows.
