![]() ![]() Suppose there is a natural light 2 a 23 a 35 a 5 irradiating on an apple. In fact, such a system can be widely used in fashion shows, painting exhibitions and commodity displays. Interestingly, the C 235 color system allows users to conveniently merge lights and colors and facilitates the design of smart lighting systems by adjusting users' preferences. A typical LED is fed with pulsed high currents for a short period of time using the pulse width modulation (PWM) technique to create modulated electronic pulses of the desired width 1. Most such involved displays in cellular phones and TVs use LED as the light source. We consider LCD (Liquid Crystal Display) technology as an example. The C 235 system facilitate potential practical applications in various areas. The compressed C 235 wheel is designed to unify CMYK, RGB, and HSV color systems using a much smaller number of raw colors (key values) to represent all 256 3 colors as illustrated in the image above. We design a compressed color wheel, called C 235 wheel, which may integrate the CMYK and RGB wheels with the compression error rate less than 1.2%. Thirdly, the CMYK wheel and RGB wheel are not interchangeable. Secondly, CMYK and RGB need 3×256 and 4×100 values, respectively, for representing colors.

The compressed C235 wheel unifies CMYK, RGB, and HSV color systems using a much smaller number of raw colors (key values) to represent all 256³ colors. General rule is that a higher power means a darker/thicker color. Since = represents a white light, we use the powers of 30 (such as 30 1, 30 2, 30 3, ⋯) to indicate the grayness levels. Consequently, code = is for color yellow (Y), code = is for color cyan (C), code = is for color yellow-green (YG), and code = is for color cyan-green (CG).Ī color in the C 235 system is also associated with a gray level for its lightness/thickness. In this color frame, code is for red color, for green color and for blue color. The C 235 color system uses the first three prime numbers 2, 3, and 5 to represent the three basic colors of red, green, and blue, respectively. In this study, we present a new color framework C 235 based on the prime number theory and Goldbach's conjecture to encode colors and colorize objects. It is challenging to distribute and allocate these many colors and hues on a color wheel, and the large number of color values may cause a huge computational burden for combining some of them to generate preferred colors. Size problems: Each of c, m, y, and k may assume 100 values, while each of r, g, and b may assume 256 values.Such issues may cause ineffective conversions among different colors. Unification problems: Letter symbols are difficult to use for unifying the RGB, CMYK, and HSV frames together.For instance, what is the complement color of R? What are the triad-complementary pairs within the 12 colors of ? Difficulties arise in various application contexts without a specific mechanism for mathematical operations. Expression problems: R, G, B and C, M, Y, K are letter symbols it is hard to use them to explicitly express the relationship between colors.While the two frames are widely adopted, they exhibit disadvantages or inconvenience for some application contexts: In the CMYK frame, each of C, M, Y and K, encoded as (c, m, y, k) has 100 values. In the RGB frame, each of the basic colors, encoded as coded as (r, g, b), has 256 values.
