merge array and count values

[greg]

I have the following array. Some values are in more than one group meaning that color belongs to more than one product.

array (size=6)
0 => string 'Beige' (length=5)
1 => string 'Blue' (length=4)
2 => string 'Green' (length=5)
3 => string 'Red' (length=3)
4 => string 'White' (length=5)
5 => string 'Yellow' (length=6)
array (size=6)
0 => string 'Black' (length=5)
1 => string 'Blue' (length=4)
2 => string 'Natural' (length=7)
3 => string 'Red' (length=3)
4 => string 'White' (length=5)
5 => string 'Yellow' (length=6)
array (size=12)
0 => string 'Black' (length=5)
1 => string 'Burgundy' (length=
2 => string 'Blue' (length=4)
3 => string 'Green' (length=5)
4 => string 'Gold' (length=4)
5 => string 'Orange' (length=6)
6 => string 'Purple' (length=6)
7 => string 'Red' (length=3)
8 => string 'Silver' (length=6)
9 => string 'Teal' (length=4)
10 => string 'White' (length=5)
11 => string 'Yellow' (length=6)

How can be merged in a way to get all values together and finally get these values counted so can get the result as seem at the end?

array (size=24)
  0 => string 'Beige' (length=5)
  1 => string 'Blue' (length=4)
  2 => string 'Green' (length=5)
  3 => string 'Red' (length=3)
  4 => string 'White' (length=5)
  5 => string 'Yellow' (length=6)
  6 => string 'Black' (length=5)
  7 => string 'Blue' (length=4)
  8 => string 'Natural' (length=7)
  9 => string 'Red' (length=3)
  10 => string 'White' (length=5)
  11 => string 'Yellow' (length=6)
  12 => string 'Black' (length=5)
  13 => string 'Burgundy' (length=
  14 => string 'Blue' (length=4)
  15 => string 'Green' (length=5)
  16 => string 'Gold' (length=4)
  17 => string 'Orange' (length=6)
  18 => string 'Purple' (length=6)
  19 => string 'Red' (length=3)
  20 => string 'Silver' (length=6)
  21 => string 'Teal' (length=4)
  22 => string 'White' (length=5)
  23 => string 'Yellow' (length=6)

Final Result

Beige (1)
Black (2)
Blue (3)
Burgundy (1)
Gold (1)
Green (2)
Natural (1)
Orange (1)
Purple (1)
Red (3)
Silver (1)
Teal (1)
White (3)
Yellow (3)
