This is an app that can convert HEX and RGB to each other. The advantage of converting between RGB and HEX is that they provide flexible and complementary color representations. RGB visually displays the composition of colors through the intensity values of red, green, and blue, making it easy to fine tune; HEX, on the other hand, is widely used in web code and other scenarios in a compact hexadecimal format. The conversion between the two not only improves work efficiency, but also meets the needs of different scenarios, achieving flexibility and convenience in color processing.
