from my expirence i know that bright yellow vomit is cursed by high amount of seaman being digested and irritating the gull bladder this also could be from eating crabs.

If you mean "brighter" as in a very bright yellow color it could be from vitamins or medications you are taking. Have you started taking a new medicine or vitamin? It can change your urine color. Eating certain vegetables in large quantities can change the color as well as dehydration, not drinking enough fluids, specifically water. That would cause your urine to turn a deep, yellow color. Other variations of yellows or red-browns can be more serious. And of course any pain, burning, itching or swelling around the urethra or discharge should be cause for being seen by your family physician.
Sodium can cause difficulties in interpreting a flame test because it is a common contaminant in laboratory materials and can produce a bright yellow flame when heated, leading to confusion in identifying the true color emitted by other elements being tested.
I take vitmain B conplex, and it makes my urine a BRIGHT yellow, almost neon, and no it's not just a couple hours after first taking them, it's the whole day, and as long as you take them. I only take the pill once a day, and it make all urinations the same color. I knew about the whole not enough water thing, but it's not a dark or deep yellow, it's BRIGHT and VIBRANT, and nothing to be alarmed about.
