Purple, my sister decorated her room in these colors and it looks GREAT!
On an artist's color wheel, green is the complement of red. Orange is the complement of blue. On a printing color wheel, cyan is the complement of red. Yellow is the complement of blue.
1) white 2) cobalt blue 3) beige
The complement of Pale blue is, a some what salmon color. A good medium between red and orange which is the complement of blue.
Red.
orange
Orange is blue's complement. They are across each other on the color wheel. If you mix them in equal parts you will get brown.
Let's start with what colors have complements red and green blue and orange yellow and purple one of the colors in the pairs is a primary (where no colors can be mixed to make that color) and the other color is a secondary that cannot be made by two other primary colors that are not of its complement (green is made of blue and yellow while it's complement is red) if you mix any two complementary colors, it will make brown. However, since brown is made of a primary (red, blue, or yellow) and a secondary (green, orange, or purple) color it doesn't have a complement because it isn't a primary nor a secondary color. Black is made of equal parts of all three primary colors while white is no color. I don't think they are considered complementary colors, but the fact that brown has no complement, they answer to the question would be no. Not every color has a complement.
magenta!
Medium blue, patterned if the shirt is plain. I wouldn't go blue on blue... same colors rarely complement each other. Consider a silver, black, orange, or even green tie, depending on the shades.
Unfortunately there is NO working cheat for it as of yet. All the listed cheats for that costume have proven to be utterly false. So, as of yet, the only way to actually get it is to complete all 180 Challenges.
White or black
