I like some of the other ideas presented so far, so here are some of theirs that I have slightly modified, and some of my own:
Part 1:
- Part name: Cheese slope with stud
- Part description: a 1x1 cheese slope with a stud on the sloped part of the element
- Part usage: Anywhere from mecha legs and arms to mounting plates on a slope like one would do with a roof.
Part 2:
- Part name: Four-armed torso
- Part description: A torso with four holes for four arms.
- Part usage: Perfect for any alien, mutant, etc. Would be very popular.
Part 3:
- Part name: Double-sided 1x1 plate
- Part description: Imagine a 1x1 plate, with studs on both sides!
- Part usage: It would be revolutionary! I can imagine dozens of new techniques that will be invented that revolve all around this one piece.
Part 4:
- Part name: Tile 1 x 1, round with groove
- Part description: A smooth stud piece, a tile 1x1 stud
- Part usage: For finishing off round structures. Detailing. Many uses.
Color 1:
- Code Name: Aqua
- Color code: #06f4f1
- Color sample:
- Color usage: This would be a replacement color for the long-gone color of "turquoise". This is one of my favorite colors, but the pieces are so rare they are extremely expensive on Bricklink. This color is a little more bluish than turquoise, but I think it would be a hit (you gotta admit, this is a sweet color!)
Color 2:
- Code Name: Trans-Neon-Pink
- Color code: #ff00ea but translucent of course
- Color sample: Don't forget that it is trans
- Color usage: This would be a very popular new color and if cockpits were created in this color, it would make a stunning appearance and I am sure that everybody would want a set with this color (I would...)
EDIT: Wow, I'm the first to suggest new colors...
