Matcha powder has different grades and these grades correspond to different colours and prices. Matcha powder is separated into ceremonial-grade tea, the highest you can find, which makes a thick, very special, intense, vibrant green tea. Then you have culinary-grade matcha with a bright matcha colour, and you have ingredient-grade, which is the lowest grade and has a slightly yellower or olive green colour. If you want a very nice, bright green colour, you could go for the culinary-grade matcha, but be aware it’s not suitable for making tea with – or just splurge on a ceremonial-grade one that you can also use for making cups of tea.
