What race is Yellow?

Nowhere in the Bible does it say that. What Jesus said is recorded in Matthew Chapter Five: “Happy are those conscious of their spiritual need, since the kingdom of the heavens belongs to them. “Happy are those who mourn, since they will be comforted. “Happy are the mild-tempered ones, since they will inherit the earth. “Happy are those hungering and thirsting for righteousness, since they will be filled. “Happy are the merciful, since they will be shown mercy. “Happy are the pure in heart, since they will see God. “Happy are the peaceable, since they will be called ‘sons of God.’ “Happy are those who have been persecuted for righteousness’ sake, since the kingdom of the heavens belongs to them.” Also, in the Bible Book of Acts we read: “God is not partial, but in every nation the man that fears him and works righteousness is acceptable to him.”—ACTS 10:34, 35. God is not like man. He does not discriminate God’s kingdom is no mere social reform. It is the government that will rule the universe. To make way for the universal rule of God’s kingdom, the Bible shows, the political governments of this world must be destroyed. Not from men will come this destruction, but from God. Declared the prophet Daniel: “In the days of those kings shall the God of heaven set up a kingdom which shall never be destroyed, nor shall the sovereignty thereof be left to another people; but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.”—Daniel. 2:44, AS. The Bible shows that Jesus will rule in this kingdom with 144,000 that God has called from mankind. It is composed of Christ Jesus and 144,000 persons taken “out of every tribe and tongue and people and nation . . . to rule as kings over the earth.” This powerful government will rule over “a great crowd” of subjects who, as the Bible foretells, also come “out of all nations and tribes and peoples and tongues.” (see Revelation 5:9, 10; 7:9) Both the rulers and the subjects are international in background, a truly united people from all nations, having divine approval.

At Matthew 5:5 is has been translated "and the meek shall inherit the Earth". So whoever you define as 'the meek' would be who you view will inherit the Earth. I can see people defining 'the meek' as a race and declaring they will 'rule' (as opposed to inherit) the Earth. All I can say is that someone either is misinterpreting it, mistranslating it, or has a really bad speech impediment.
