I have created a color palette named “Vibrant Harmony” which includes a vibrant primary color of orange, complemented by secondary colors of bright yellow and bold pink. The background colors range from soft light greys to deep charcoal greys for both light and dark themes. Additionally, there are light and dark border colors to harmonize with the rest of the palette.

Do you have any specific preferences for the saturation levels of the colors or any other requirements for the color palette?
