✔ Center (Circle):

- `12 + 14 = 26` → Brown

✔ Petals:

1. `11 + 3 = 14` → Light Yellow
2. `4 + 18 = 22` → Orange
3. `14 + 8 = 22` → Orange
4. `19 + 3 = 22` → Orange
5. `10 + 10 = 20` → Dark Yellow
6. `1 + 21 = 22` → Orange
7. `14 + 0 = 14` → Light Yellow
8. `4 + 18 = 22` → Orange
9. `6 + 14 = 20` → Dark Yellow
10. `11 + 11 = 22` → Orange
11. `12 + 2 = 14` → Light Yellow
12. `12 + 10 = 22` → Orange
13. `14 + 6 = 20` → Dark Yellow
14. `15 + 7 = 22` → Orange
15. `10 + 4 = 14` → Light Yellow
16. `11 + 9 = 20` → Dark Yellow
17. `6 + 9 = 15` → Dark Green
18. `0 + 14 = 14` → Light Yellow
19. `2 + 13 = 15` → Dark Green
20. `11 + 14 = 25` → Light Green
21. `8 + 7 = 15` → Dark Green
22. `15 + 10 = 25` → Light Green
23. `5 + 10 = 15` → Dark Green
24. `2 + 12 = 14` → Light Yellow
25. `17 + 5 = 22` → Orange
26. `13 + 7 = 20` → Dark Yellow
27. `22 + 0 = 22` → Orange
28. `8 + 12 = 20` → Dark Yellow
29. `11 + 4 = 15` → Dark Green
30. `21 + 4 = 25` → Light Green
31. `0 + 15 = 15` → Dark Green
32. `12 + 13 = 25` → Light Green
33. `12 + 3 = 15` → Dark Green
34. `25` (already written) → Light Green
35. `15` (already written) → Dark Green
36. `15` (already written) → Dark Green
37. `3 + 8 = 11` → Dark Blue
38. `13 + 4 = 17` → Light Blue
39. `0 + 11 = 11` → Dark Blue
40. `1 + 16 = 17` → Light Blue
41. `1 + 10 = 11` → Dark Blue
42. `5 + 12 = 17` → Light Blue
