输入红、绿、蓝颜色级别（0..255）并按 转换 按钮：
R、G、B值除以255，将范围从0..255改为0..1：
R' = R/255
G' = G/255
B' = B/255
黑色(K)由红色(R')、绿色(G')和蓝色(B')计算得出：
K = 1-max(R'， G'， B')
The cyan color (C) is calculated from the red (R') and black (K) colors:
C = (1-R'-K) / (1-K)
The magenta color (M) is calculated from the green (G') and black (K) colors:
M = (1-G'-K) / (1-K)
The yellow color (Y) is calculated from the blue (B') and black (K) colors:
Y = (1-B'-K) / (1-K)
