Can you help me with the cipher?

Question

Encryption

Hello! A friend asked me this puzzle. On 5 different videos showed 4 digits. He showed them with cards of different colors. No more information. The solution is always simple (already guessed a lot of different ones). Any ideas? :)
Numbers: 4825 3543 9061 8136 0479
Colors: ZHZK ZHZKK ZhKZK ZhKZZ ZhKZZ
Zh - yellow, R - red, G - green.
UPD. There is a hint: As you noticed, the first color in the blocks is yellow. All other cards are green or red. And that's just two colors.

Answer 1

If someone is still interested and came to see the answer. I found a solution!
The idea is that each tetrad begins with the letter J (yellow color). The rest of the colors change. Based on the hint, it is worth noting that there are only TWO such colors. Red and Green. Guessed? That's right, these are opposites, like at a traffic light, like ON-OFF, STOP-GO. But in the riddle there are only numbers and colors. We need to turn colors into the context of numbers. So....opposites and numbers. I tried to consider both 0 and 1, but it turned out to be wrong. Then I assumed that it was + and - and it turned out to be true. And then everything is simple. Yellow is everywhere, and we push off from it.
The first tetrad is 4825 and the colors are Y3ZK = Y++-. Answer: 4 + 8 + 2 - 5 \u003d 9. And 9 is the serial number of the desired letter in the alphabet Z. And further by analogy. We get an answerCASTLE .
