9x9 Domino 3D Pyramid with colored Layers! (Personal Best, Almost 500 subs special)

Before posting comments, I want to note some things: 1) There is a difference between a 2D and a 3D pyramid. A 3D pyramid is visualized as an object if you trace the dominoes mathematically, but a 2D pyramid behaves as a wall (simple isosceles triangle). 2) There are nine colors total, with a contrary color motion after the 9th layer. It goes on order: magenta, blue, yellow, orange, green, red, black, cyan, and white. However, white is not repeated. 3) There are mathematical formulas I have, given size n: a) With size n, there are 2n - 1 layers total. b) With size n, the amount of dominoes required to build (regardless of color) is t(n + 1) = t(n) + 2n^2 + 3n + 1, where t(1) = 1. You might want to use recursion in this case. c) For every odd layer, these numbers are perfect squares (that is, the numbers whose square root is an integer. 9 and 25 are perfect squares for example. And square root of 9 and 25 are 3 and 5). 4) Unfortunately, each color (excluding white, since I have 200 white dominoes) has 100 dominoes total. Therefore, I have 1100 dominoes total. 5) No external objects are used. Additionally, no external domino tricks are used. 6) This building is emotionally painful, and the biggest problem is placing dominoes properly. It took more than 2 hours to build a 9x9 domino pyramid, with taking breaks to accommodate nervousness. Once again, thanks for everyone supporting this channel!
