Sea Urchin Roe (uni) -- is a mixed yellow and brownish color okay?
It is often very hard to even get uni in many places (which is blamed on sometimes weather and/or sea otters) and even when I can order it, it is not of uniform golden color but sort of mixed. I suspect this might be (my research yields) "vani" which is a mixture of chunks that have broken off and are collected together and sold.
I am not only somewhat picky about looks but even more concerned about safety and of course taste. Years ago, I don't recall getting anything other than just pure chunks of golden, no brown, uni.
Is the brown just normal color range or is it somewhat spoiled or is it even, shudder, part of the sea urchin that is not actually uni?
I did find this by searching for sea urchin roe, not "uni" and it sounds like brown is not a good thing: https://www.researchgate.net/publication/223038425_Factors_causing_Brown-colored_gonads_of_the_sea_urchin_Strongylocentrotus_nudus_in_northen_Honoshu_Japan

It should always be bright yellow to orange. The brownish hue you are talking of makes me worry about age and age equals increased bacterial content. https://harborfish.com/what-is-uni-a-complete-guide-to-sea-urchin/

What color should sea urchin be?
Sea urchins are spiny-shelled echinoderms. They are closely related to sand dollars and starfish. Uni, pronounced oo-nee, are actually sea urchin roe. These bright yellow to bright orange lobes are considered a delicacy to some.How can you tell if a sea urchin is good?
Depending on the variety, diet, and gender, good uni is firm but melts in your mouth with its rich and creamy sweetness, and is just a little bit slimy (a good slimy, I swear!). It's almost a bit custard-like \u2013 but lighter. And important to note, good uni is never fishy but instead, has delicate traces of the ocean.What is the yellow stuff in sea urchins?
Though typically called sea urchin roe, uni is actually the sex organ that produces roe, sometimes referred to as the gonads or corals. Five strips or \u201ctongues\u201d of uni live within the structure of an urchin. They are usually orange or yellowish, and do resemble tongues, with the consistency of a firm custard.How do you know if uni is fresh?
You'll know that uni is fresh when it keeps its shape and isn't mushy. Uni is soft, melts in your mouth but should still have a little bit of bite, much like tofu.How Sea Urchin (Uni) Is Processed Commercially — How to Make It
