However, when we analyze the color next to its other triadic colors, #E37858 (a shade of "<shade>Burnt Sienna</shade>") and #58E378 (a shade of "<shade>Ufo Green</shade>"), the resulting palette becomes harder and cooler than the complementary color palette and changes from the color index category of "<category>dynamic</category>" to the "<category>elegant</category>" category. Specifically, the new triad is most suggestive of <term>powers</term> and <term>flourishing</term>.
