The 16 prompts below may be separated into 4 groups.
Additionally, there is a word absent from the wall which may be placed in all four of those groups.

#F0F8FF (240, 100%, 50%) (255, 215, 0) Aqua
(250, 235, 215) Lime #000000 (0, 100%, 25%)
(39, 85%, 95%) (230, 230, 250) Orchid #FA8072
SlateBlue #EE82EE (39, 77%, 83%) (64, 224, 208)

Can you identify the four groups?
What new word can be placed in all four of those groups?

Author note: You can try to have the groups be what they look like, but it won't help at all for the final word. (X, Y%, Z%) are in HSL.


SlateBlue is a very peculiar name, one amongst 140 others.

One of the groups has an edgy side.

One of the groups has a similar head and tail.

One of the groups was inspired by nature.

    $\begingroup$ In case this helps save anyone some time, using this site the 16 names are: rot13(NyvprOyhr, Oyhr, Tbyq, Ndhn, NagvdhrJuvgr, Yvzr, Oynpx, Znebba, ByqYnpr, Yniraqre, Bepuvq, Fnyzba, FyngrOyhr, Ivbyrg, Jurng, Ghedhbvfr) $\endgroup$

    $\begingroup$ @Stiv Mhm, the contents are correct, I believe the second part of the first hint can't refer to any other groups or colors (or at least I hope so). $\endgroup$

1 Answer 1


The first thing to note ...

... (and which several commenters noted early on) is that all items on the wall define X11 or Web colours. (Both sets are similar, but (0, 100%, 25%) is not a named X11 colour; as a Web colour, it's maroon. But the X11 wiki page has a better tabular overview, so I linked that, too.)

Stiv has helpfully identified all 16 colours:

    Alice Blue          Blue            Gold            Aqua
    Antique White       Lime            Black           Maroon
    Old Lace            Lavender        Orchid          Salmon
    Slate Blue          Violet          Wheat           Turquoise

The four groups:

Groups in Connect Walls can overlap, but there must be four items in four different groups. Ideas for the groups:

(1) Colours that also have a Dark variant: Dark Blue, Dark Orchid, Dark Salmon, Dark Slate Blue, Dark Turquoise and Dark Violet are valid Web colour names. The "edgy side" mentioned in the hint is a dark side.

(2) Colours that are named after plants: Lime, Lavender, Orchid, Violet, Wheat. (Arguably this is the group that is "inspired by nature")

(3) Colours where at least one of their RGB components is zero: Blue (#0000FF), Lime (#00FF00), Gold (#FFD700), Aqua (#00FFFF), Black (#000000) and Maroon (#800000).

(4) Colours whose names begin and end with a vowel: Alice Blue, Aqua, Antique White and Old Lace. I think this is the group that has "has a similar head and tail".

Sorting it out:

The overlap can be sorted out:

(1) Dark colours: Blue, Salmon, Slate Blue, Turquoise
(2) Plants: Lavender, Orchid, Violet, Wheat
(3) Zero RGB: Gold, Lime, Black, Maroon
(4) Vowels: Alice Blue, Aqua, Antique White, Old Lace

The missing word:

I think the missing word is Orange, which is the name of the Web colour #FFA500: Dark Orange is a Web colour name; an orange (tree) is a plant; the blue component is zero and it starts and ends with a vowel.

(In a comment, Stiv suggests Olive (#808000), which also fits, except that the corresponding dark colour is called Dark Olive Green, not just Dark Olive.)

  • $\begingroup$ With some leeway Maroon could fit into 2. (marron, chestnut, and this random page agrees) $\endgroup$ Jun 15 at 19:43
  • $\begingroup$ Yeah, maybe. And then move something else from group (2) to (3)? I mean, qua isn't so hot as English word compared to the others. Remove more than one letter at the front to get "vender" (ugh!) or "chid"? $\endgroup$

  • $\begingroup$ Groups 1 and 4 are correct, Group 2 has one of its member missing/switched with another, and Group 3's definition is sadly not true.

  • $\begingroup$ Well done for persevering - my way of thinking was more aligned with your first attempt minus the 'dark' group, so I was actually two groups off in the end +1 $\endgroup$
