Run and debug it

Unpacked, ungolfed, and commented, it looks like this.

" vibgyor"  string literal
,^:m        increment input, then repeat literal to that length
|]          get all prefixes
Mr          rectangularize, transpose array of arrays, then reverse
            this is the same as rotating counter-clockwise
m           map over each row with the rest of the program, then implicitly output
            the stack starts with just the row itself
  _h        push the first character of the row
  _r        push the reversed row
  L         wrap the entire stack in a single array
