You can tell if your daughter might be color blind by observing if she uses incorrect colors in drawings (purple grass, brown leaves), struggles to name or differentiate colors (like blue/purple, red/green), avoids coloring tasks, or has trouble with color-coded activities like sorting blocks, especially around ages 4-6; a professional eye exam is needed for a formal diagnosis.
