It all depends on data definition. What makes a color a favorite color? If you can answer that question you can solve it.
For example:
If I order 2 blue shirts and 1 red, is blue my favorite color? Then you should count the colors and pick the one with the most counts.
Maybe I'm allowed to pick my own favorite color?
So if I order 2 blue shirts and 1 red my favorite color can be yellow?
One question and so many possibilities
sorry I expressed myself badly.
TABLE COLORS
row1 -> BLUE
row2 -> RED
row3 -> GREEN
row4 -> BLUE
the query must return BLUE because it is the most used data
one simple way
declare @sample table(color varchar(10))
insert into @sample
select 'BLUE' union all
select 'RED' union all
select 'GREEN' union all
select 'BLUE'
select top 1 count(1), color
from @sample
group by color
order by 1 desc
or
SELECT distinct FIRST_VALUE(color)
OVER (ORDER BY COUNT(color) DESC) AS MostCommonColor
FROM @sample
group by color
