However, when we analyze the color next to its other triadic colors, #3E291D (a shade of "<shade>Bistre</shade>") and #1D3E29 (a shade of "<shade>Phthalo Green</shade>"), the resulting palette becomes softer and cooler than the complementary color palette and changes from the color index category of "<category>casual</category>" to the "<category>elegant</category>" category. Specifically, the new triad is most suggestive of <term>conservative</term> and <term>ancient</term>.
