Group 1: brown, white, green, gray, ___________
Group 2: all other colors
Exactly one other color belongs in group 1. Which color is it (i.e. fill in the blank), and why?

$\begingroup$ I think fourth one maybe black or blue $\endgroup$ – Udhay Titus Dec 17 '19 at 12:42

1$\begingroup$ Is group 1 restricted to five elements? $\endgroup$ – Thomas Markov Dec 17 '19 at 13:02

1$\begingroup$ @ThomasMarkov, there are only five colors that belong in group 1. It's not restricted to five, but there is a reason that those five colors belong in a group to which no other colors belong. I will edit the question for clarity. $\endgroup$ – Gary S. Dec 17 '19 at 13:08

$\begingroup$ Is the sports tag applicable here, by any chance? $\endgroup$ – Stiv Dec 17 '19 at 13:10

2$\begingroup$ I think you're on the right lines with this but I also think the answer must be more specific than this - Gold is also fairly common in some circles... My own feeling is there will be a connection with players on a particular sports team or leaders of a particular country - something like that... $\endgroup$ – Stiv Dec 17 '19 at 14:25

2$\begingroup$ @Stiv I agree this is a poor answer (Gold, Silver, Blue, and others enjoy some currency). I posted it because I suspected it was the answer the asker had intended. $\endgroup$ – msh210 Dec 17 '19 at 14:31

3$\begingroup$ No criticism of the quality of your answer intended :) I'd been thinking along similar lines but had been sure there must be more to it than a subjective 'most common' solution (Where do you draw the cutoff line? Which country? Which data source?). I'm just a touch disappointed there wasn't more to it, that's all...! $\endgroup$ – Stiv Dec 17 '19 at 14:36

3$\begingroup$ ^ @GaryS. Not a great idea to post links that auto-download files to people's devices - would be best to provide a link to a website from which visitors could choose to start the download or not... Thanks. $\endgroup$ – Stiv Dec 17 '19 at 14:40

1$\begingroup$ @Stiv, you're right. Here's a link to a web page: bit.ly/2RZGW7K $\endgroup$ – Gary S. Dec 17 '19 at 14:48

If you remove the second and the fifth letters from the colours, you get 'bow', 'wit', 'gee', and 'gay', which are all valid words.
Therefore, according to this logic:
Violet should fit the rule since applying the rule gives volt.

4$\begingroup$ Beige and daisy and blonde and spice and blood fit also, then, and doubtless more colors do, too. $\endgroup$ – msh210 Dec 17 '19 at 13:44

$\begingroup$ You're right. It will be better to wait for a hint before posting an answer. $\endgroup$ – Toby Mak Dec 17 '19 at 13:49

$\begingroup$ Great idea! Very clever. But as @msh210 rightly points out, this is not what I have in mind. $\endgroup$ – Gary S. Dec 17 '19 at 13:53
