Before we get to fixes, let's talk about why color matters. Matcha comes from shade-grown tea leaves. The shade boosts chlorophyll, which gives the powder that bright green hue. When you see a dull yellow or brown tint, it usually means:

• Older leaves (harvested later in the season)
• Poor storage (exposed to light or air)
• Over-processing or low-quality grinding

But here's the trap: you can't always trust product photos. Many brands use editing to make their matcha look brighter than it really is. So the first step is to set up a fair test.

I told my friend to do this: scoop a teaspoon onto a white plate, flatten it, and look at it under natural light. No phone filters, no studio lights. That's your baseline.

Then, make a small bowl. Whisk it with water at about 170°F. Watch the color as it froths. Good matcha should be a vibrant, slightly creamy green—not neon, not muddy.
