The problem with testing in one scene
Most HUD color choices are made in one lighting condition, usually whatever time of day it was when the owner tested. GTA V does not stay in one condition. The same street goes from bright afternoon sun to near black at 3 a.m., and rain or fog flattens everything in between. A pale gold accent that glows at night can disappear against a sunlit sidewalk, and a deep navy panel that looks elegant during the day can vanish into the night sky. Your minimap and weapon wheel both sit on top of the world, so both need colors that survive the whole cycle.
Give every piece a solid base
The most reliable way to keep a HUD readable is to put text and icons on a base that you control, instead of relying on whatever the world behind them looks like. On a minimap that means a background with enough opacity. On the weapon wheel it means the base, panel, plate or glass color. Dark bases in the charcoal to near-black range work in almost every scene, because daylight rarely gets dark enough to swallow them and at night they read as a clear shape. If you prefer a light or glassy look, keep the icons and text dark enough to hold against a bright sky.
Choosing an accent that works in both
Accent colors with mid to high brightness and clear saturation hold up best: amber, signal orange, cyan, acid green, a clean red. Very dark accents such as deep burgundy or navy look rich but fade at night, and very pale ones such as pearl or champagne can wash out in sunlight. If you love a subtle accent, use it on a dark base where it still has contrast. Keep the same accent on the minimap's roads or route and the wheel's selected slot. When players learn that one color means the important thing, they find it faster in any light.
Text and numbers deserve their own colors
In the weapon wheel studio the weapon name, ammo count and clip count each have their own color control, separate from the accent. Use that. Numbers need to be read instantly in a fight, so they should be the highest contrast element on the wheel, usually white or a very light tint. Match that text color to the street labels on your minimap. If you want the accent to show up in text, use it on one element, such as the clip count, and keep the rest neutral. This keeps the HUD calm while the parts that carry information stay sharp.
Test like a player
Use the scene switcher in the studio's live preview to look at your wheel against different backgrounds before you order. Open it with TAB, move through slots, check it in vehicle mode, and compare it with the original GTA wheel, which was built to be readable everywhere and makes a good reference. Then look at your minimap in the same conditions on your server. If both pass in a bright scene and a dark one, you have a HUD players can use for hours without squinting. If one fails, adjust the base or text color rather than the accent, since that usually fixes it.
