Sorry for asking about such minor issue, but I have another idea below.

Among all these colors the least bad is LightSalmon,
but it has the same saturation as Orange, not as much lighter Gold
that would be the best choice.

We can call it "hi-redgold" because such thing really exists:
https://en.wikipedia.org/wiki/Red_gold

(defface hi-redgold
  '((((min-colors 88) (type x w32 ns)) (:background "gold"))
    (((min-colors 88)) (:background "orange"))
    (((min-colors 16)) (:background "red"))
    (t (:background "red")))
  "Face for hi-lock mode."
  :group 'hi-lock-faces)
