A nail color chart is a fast way to turn what you are seeing into a shortlist of likely reasons. Pick the color closest to yours below, read the common causes, and jump to a full guide. Treat it as a starting point, not a verdict, since color is only one clue among several.

The chart
If the interactive tool has not loaded, use this quick reference:
- White flecks or spots. Usually old minor knocks growing out, not low calcium. See white spots on nails.
- Yellow. Most often fungus or staining from polish and smoking. See yellow nails.
- Pale or washed out. Can follow anemia or low circulation, especially across all nails.
- Blue or purple. May signal low oxygen or a circulation problem, worth prompt attention if sudden.
- Green. Often a bacterial growth under a lifted nail, common in people whose hands stay wet.
- A brown or black line. Usually harmless pigment, but a single widening band needs a check. See dark line on a nail.
- Red lunula or red streaks. Splinter-like red lines or a red half-moon can relate to several conditions and are worth mentioning.
- Half white, half pink. A nail split into two zones can be linked to kidney issues and deserves a doctor's look.
How to use this chart
Start with color, then add context. Ask yourself three questions: Is it one nail or many? Is the texture changing too, such as thickening or lifting? Do I have other symptoms? One nail with a local cause is reassuring. The same color across many nails, or color plus texture change, is what moves an item up your list.
When to see a doctor
Book a visit if you see a single dark band that is widening, a nail turning blue or fully white, green discoloration with lifting, or any color change paired with pain, bleeding, or feeling unwell.
Frequently asked questions
What do different nail colors mean?+
Each color hints at a different cause. White flecks usually mean minor trauma, yellow suggests fungus or staining, pale can follow anemia, blue points to low oxygen or circulation, and a dark line is usually harmless but sometimes needs a dermatologist.
Is a nail color chart a diagnosis?+
No. A chart narrows down likely causes and tells you when to seek care. It cannot replace an exam, especially for a single dark band or a nail that is changing.
How accurate is reading nail color?+
Color is a useful clue but only one piece. Pattern, how many nails are involved, texture changes, and your symptoms matter just as much.
