Answer: This is an example script of how you can achieve this result. This is a naive query - and may not fully encapsulate what you are trying to achieve within the overall grouping operations.
create table #temp1 (id int, color varchar(10) ) insert into #temp1 select 1, 'red' union select 2, 'red' union select 3, 'red' union select 4, 'blue' union select 5, 'blue' union select 6, 'blue' union select 7, 'black' union select 8, 'black' select color, count(color) as 'color_numbers' from #temp1 group by color drop table #temp1
