L.; yes this can be very difficult but it can also be very fun, ive done a few things with color that turned out well, one is you can do a wainscoating thing where one color meets up the wall to the other color, instead of this wall this color and that wall that color, you can do all walls half like top half one color, bottom half another, or you can do a shape thing on the wall, i did a room with polka dots on it, in a contrasting color, but that more for a girls room, we did one wall with large dots that we drew around bowls i found around the house 7 diff sizes, and then painted in the circle with other color, turned out great, but you can use other shapes as well, like brown walls with red squares or triangles intermixed with each other on one large wall, or you can do a splatter effect, i did this with a white room, and then splattered the color they wanted in the middle of room all the way around, i used my hands to make the splatter, i dipped my fingertips in the paint and splattered them like at waist hight it formed like a border around the room, a white wall with brown and red splatters could be cool looking accented with sheets and pillows and blankets, you dont have to paint all the walls, you can accent white room in those colors, keep your splatter even all the way around, also in one of my boys room i made a large stripe but not your average sideways one like a border, i made a continuous stripe that went around the room but broken, like / on one wall, and connected that over the ceiling, and down the other wall \ like this angle, i broke it up some walls had partial lines through it, but it appeared that they connected it was a 1 foot stripe width went up on angles up one wall down another as if it were bounced off itself at the edge of wall, if you need more ideas or want to talk more about these feel free to contact me at ____@____.com thanks D. s
