Thanks for all these additional details.
I can understand your concern.
Well, . Change in finger color and nail as Orange, could be due to something that has been absorbed into the skin from the external environment and if so should clear up on its own in 7-10 days.
The other possibility would be the first stage of paronychia which is a bacterial infection of the nail folds - this can make the nail folds look very red / orange but is usually associated with significant pain in the area.
If you have associated pain and swelling, then you would need antibiotics.
In case there is no pain, the chances of infection are very slim.
This could also be related with- fungal infection. To make a diagnose, a clinical examination and KOH and culture test would be necessary.
If the diagnosis is confirmed by tests then treatment with anti-fungal medications can be started.
You would need medications like- Fluconazole griseofulvin, terbinafine, and itraconazole.
Other common cause for this are- excess carotene either in the diet or in supplements or both.
It's more often seen in vegetarians. If that's the case, cutting back on the intake will resolve the problem. It's also sometimes seen in diabetes, liver and kidney conditions, and thyroid conditions. Your doctor can check this out and determine if there is an organ problem here.
Hemochromatosis, an iron storage disorder, could also cause this.
Foods that are high in Vitamin A, or beta-carotene, can cause skin and nail discoloration. These would be foods like carrots, cantaloupe, pumpkin, summer squash.
I would suggest you to get a clinical examination done by your doctor. You would be advised treatment accordingly.
Hope this helped.
