i don't have the patience to read through the entire thread, so I apologize if I'm repeating what someone else has said, but here's my two cents:
FR has refused to give us single-color randomizers despite people asking for them for years. The way FR's mechanics are set up, I actually think this is fine. Dragons can only have three colors, and one of them is invisible unless you specifically choose to make it visible. Finding a G1 dragon with two pretty colors isn't really that difficult. With the addition of some pretty wild color accenting in recent markings over the last couple years, it's easier than it's ever been to take a G1 with three random colors and make it work.
LW is different in several ways. Wolves have four color slots (five if you count the eyes, which are also changeable), and every single one of those colors is visible on a wolf no matter what. We can't hide an ugly tertiary or quaternary color by not giving it a gene. And LW genes have no color accenting at all: you get exactly what the color picker gives you, maybe with a little bit of a gradient into the next marking color. For all of these reasons, giving us an item to randomize a single slot of a wolf's colors is less "removing all challenge from the game as a breeding sim" and more "a reasonable QOL item to bridge a gap where the math fails us".
To drive home my point, I'll end with some numbers.
FR has 177 colors. That means 177 different possibilities in each of three slots. 177 x 177 x 177 = 5,545,233 possible combinations of colors on a dragon. Some of these are going to be very nice, some are going to be hideous no matter what, and some are going to be workable in one way or another. 5.55 million.
LW has 201 colors. That's 201 different possibilities in each of five slots. 201 x 201 x 201 x 201 x 201 = 328,080,401,001 possible combinations. 328 billion.
Now we all know that at numbers this large, the human brain struggles with scale. A million seconds is twelve days. A billion seconds is 32 years.
If I hatched one dragon egg per second, it would take me about two months (66 days) to get one of every possible color combo. (I'm bending probability here, but bear with me.)
If I found one wild wolf per second, it would take me ten thousand years to get one of every possible color combo. (1 bil seconds = 32 years. 32 years times 328 billion combinations = 10,496.)
Now obviously nobody is trying to get every color combo, but my point is the odds of randomly getting a wolf that looks nice in all four main colors is several orders of magnitude more difficult than getting a dragon that looks nice in all three.
Please, please give us an item to randomize one slot at a time. From a business perspective, I can guarantee you you'll make more money selling those than insisting on keeping only the five-slot besprinklers. Once your users take a look at the odds, besprinklers start looking less like a fun gamble and more like a complete waste of moonstones.
328 billion color combinations.
