This is an idea I have had in my mind for quite some time now. Could it be possible to make a certain option in the color crafting dialog that chooses a random color from the full list of colors (160+).

This could be really neat, especially when the player wants to do a complete style revamp, and wants to scroll randomly on the color department until he/she finds a color of his/her liking.

That seems a lot of effort for something you could just toss a die for.

The solution:
For that I suggest a d4 followed by a d4 and then a d12.

The Logic:
There are 176 colours abailable.
The first roll divides them in four, grouping them per 44.
The second roll divides the groups in four again, creating a group of 11.
The last roll chooses which of those 11 win (when rolling a 12, roll again)

The Example:
Starting the first colour, let's say a metallic one:
I roll 2, 3, 12. I'll have to reroll the 12 and get a 8.
The two means I'll be having a colour between nr 45 and 88.
The three means a colour with nr between 67 and 77.
Then the eight means colour 74 is the winner: Lush Faded Plum.

The Table:
First Roll Second Roll
1: 1-44

1: 1-11
2: 12-22
3: 23-33
4: 34-44

2: 48-88

1: 45-55
2: 56-66
3: 67 - 77
4: 78 - 88

3: 89-132

1: 89 - 99
2: 100 - 110
3: 111 - 121
4: 122 - 132

4: 133-176

1: 133 - 143
2: 144 - 154
3: 155 - 165
4: 166 - 176

Why not make it so the entire outfit changes each part to a random number between 1-176?

Even in that form it seem's more laziness then actually useful.

That's awfully complicated and time taking for one random colour... o_O
