Explanation

To solve the question "What is the colour of the fresh grass?" based on the provided statements, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Identify the Color of Fresh Grass:**
- The common knowledge is that fresh grass is typically green in color.

2. **Analyze Statement I:**
- The first statement provides the following information:
- Blue is called green.
- Red is called orange.
- Orange is called yellow.
- From this statement, we see that "green" is referred to as "blue." However, it does not provide any information about what "green" is called or what the actual color of grass is in this context. Therefore, this statement alone is insufficient to determine the color of fresh grass.

3. **Analyze Statement II:**
- The second statement provides the following information:
- Yellow is called white.
- White is called black.
- Green is called brown.
- Brown is called purple.
- Here, we see that "green" is referred to as "brown." This means that according to this statement, fresh grass, which is green, is actually called brown. Thus, this statement alone is sufficient to determine the color of fresh grass.

4. **Conclusion:**
- Since Statement I does not provide enough information to determine the color of fresh grass, but Statement II does, we conclude that the color of fresh grass is brown according to the definitions provided in Statement II.

### Final Answer:
The color of fresh grass is **brown** according to the information given in Statement II.
