We've observed that the automatic color selection, particularly for shades like yellow and green, often results in colors that appear dull rather than fresh. To improve this, we propose the addition of a manual color shade selection feature, similar to what is offered by leonardocolor.io. Currently, the colors are mathematically calculated uniformly, which often leads to less appealing yellows. By incorporating a manual selection option, we can ensure more vibrant and aesthetically pleasing color choices.
