In a color sequence, Orange acts as a hinge rather than a destination. Place yellow before it and the transition feels sunlit; follow it with red and the same swatch begins to feel hotter. This makes it handy for diagrams or illustrations that need a readable path through warm hues.
For a split-temperature palette, set Orange against Azure; the blue keeps the warm section from closing in on itself. Coral continues the warm route with a softer, pinker turn.
The standard web value is easy to reproduce on screen, but the broad label Orange covers many different inks and paints. If matching a physical reference matters, use #FFA500 as the digital target and make a small print proof before approving the final color.
