The colour indicates the ranking of the proposed principle to solve the contradiction:
1st,
2nd,
3rd,
4th.
This ranking reflects the frequency of occurrence of the principle in the analysed patents for this type of contradiction.
When a principle appears in first position, it means that it is statistically the most used in the patents studied for this type of problem.
