(10) There are 8 black, white, and yellow chopsticks each. Without looking, take out the chopsticks arbitrarily to ensure that there are at least two pairs of chopsticks of different colors. Then, at least $\qquad$ chopsticks need to be taken out to achieve this.
1011 Hint: Among 11 chopsticks, there must be a pair of the same color, let's say yellow. Then, there are at least 3 black or white chopsticks, among which there must be a pair of the same color, either black or white. Therefore, 11 chopsticks are sufficient to ensure success. However, fewer than 11 will not work, for example, if only 10 chopsticks are taken, it is possible to have 8 yellow, 1 black, and 1 white, which does not meet the requirement.
