How do you check an undertone with a phone camera?

I am trying to reduce my wardrobe to pieces I actually combine and would like the palette to be practical rather than exhaustive. Warm olive, rust, and cream are consistently flattering while optic white and cool gray make me look tired. Those comparisons point broadly toward Autumn although very orange camel and yellow mustard are not convincing. I used a [url=https://hairdye.top]what is my color palette[/url] as a starting point, but I want to verify it with clothes I already own. Ideally I need a pair of neutrals, three accents, and one pale shade that can all be worn together across seasons. Deep chocolate works better on me than solid black but I am unsure whether navy could still function as a second neutral. For accents I am considering teal, brick red, and forest green rather than buying several nearly identical earth tones. What is the simplest way to check that these shades belong together under both daylight and ordinary office lighting? Advice from people using a limited palette would help me most, especially any unexpected neutral that increased the number of combinations.
