The color of urine is determined on how concentrated the urine is. It's from all of the toxins being excreted. In the morning it's a fasting urine and you haven't drank fluids all night. So it's concentrated and dark yellow. During the day, you drink and dilute the urine so there more water in the urine, less concentrated and lighter in color

It can be. The first void of the morning is usually the most concentrated, which helps when trying to do pregnancy tests or microalbumin-creatinine ratios.
Can your urine be dilute first thing in the morning?

Why there is a limit of 500 ml of urine production of kidney?
Kidney can form concentrated or dilute urine. But it has got it's own limitations for the same. So it can produce 22 liters/ day of urine to it's maximum capacity and minimum 500 ml/ day of urine is required to excrete to solutes including nitrogenous waste products. That is the capacity of kidney to concentrate urine.
Why would urine passed in the morning be a darker colour than urine passed in the rest of the day?
Because it's been in the bladder all night (probably for eight hours) and is more concentrated. Urine passed through the rest of the day is rarely in the bladder for more than an hour at a time.
Why is urine darker on a hot sunny day?
Urine appears darker on a hot sunny day primarily due to dehydration. When temperatures rise and you sweat more, your body loses fluids, leading to a concentration of waste products in the urine. As a result, the urine becomes more concentrated and takes on a darker hue. Staying hydrated by drinking water can help maintain lighter urine color.

Just make sure to follow any specific instructions provided by your healthcare provider.

Should I wait until all the coffee I drank today is out of my system before I take a pregnancy test?
The coffee should make no difference. In the directions of most pregnancy test it advises to use a morning specimen. This means as soon as you wake up in the morning, the very first time you urinate that day, do the test. That is when the urine will be the most concentrated with hormones.
