Tower Scoring Clarification

If a high rise tower is built does the entire tower have to consist of only a single color block. For example, if you have the red base block and stack Red, Red, Red, Green, Green, Red you would technically have a total of five red blocks (red base plus four additional red blocks). Would this count as a multiplier of five or do the green blocks in some way impact the scoring?

Thank you!

During Teamwork Matches Highrises must be of uniform colour. In the example you’ve described, your scoring multiplier would be 3. This is because you have 3 red blocks stacked, before a non red block shows up.
