With the popularity of network, network instructional platform, as a kind of new learning means are thriving, and it also caused the attention of many scholars and research both at home and abroad. As to the discussion of online course artistry, especially the study of the color collocation of the network instructional platform is also more and more. But much of the research focuses on the theoretical level, such as research of color principles and research of color collocation. Most of these studies based on the theoretical arcane, have a far of contact with the color collocation of the practice in the design of network instructional platform. At the same time as the result of these theoretical research, on the basis of the universality principle of color theory, often not well combined with the interactivity of network instructional platform, which is strong, dynamic media, as well as the combination of a variety of media. At the same time, these studies did not focus on essential characteristics of the network instructional platform, which is a teaching tool, because of this feature, it has to complete the various tasks of teaching. So this article will explore by using the method of literature research and survey of the application of network instructional platform of color matching. By analysis of the actual case, the problems in the color collocation of the network instructional platform are presented, and good application of the principle is proved. Finally we will also discuss the application of color matching software on the network instructional platform, to further understand the principle of color collocation in the design of network instructional platform, expecting to further discuss and solve the problem of the network instructional platform design of color matching.
