Question: What act for Innocent Records achieved Platinum sales and shares its name with a primary color in the RGB color model?

<P0-S0> Blue is the colour between violet and green on the spectrum of visible light. <P0-S1>  Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength appear more violet, while those with a lower frequency and a longer wavelength gradually appear more green. <P0-S2>  Pure blue, in the middle, has a wavelength of 470 nanometres. <P0-S3>  In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. <P0-S4>  Red and blue mixed together form violet, blue and yellow together form green. <P0-S5>  Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor. <SEP> <P1-S0> Innocent Records was a pop record label created to cater to for EMI's Virgin Records more pop oriented acts. <P1-S1>  Following the success of the Spice Girls, Virgin Records decided to delve into the pop market. <P1-S2>  In doing so they poached Hugh Goldsmith from RCA Records (famous for steering Take That's initial flagging sales, to a multi-platinum act). <P1-S3>  They let him launch his own Virgin Records offshoot. <P1-S4>  His first signing was Billie Piper, followed by Martine McCutcheon, along with several dance acts Todd Terry to name one. <P1-S5>  The label continued to thrive well into the mid-2000s with Atomic Kitten and Blue achieving Platinum sales. <SEP> <P2-S0> The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. <P2-S1>  The name of the model comes from the initials of the three additive primary colors, red, green, and blue. <SEP> <P3-S0> A color space is a specific organization of colors. <P3-S1>  In combination with physical device profiling, it allows for reproducible representations of color, in both analog and digital representations. <P3-S2>  A color space may be arbitrary, with particular colors assigned to a set of physical color swatches and corresponding assigned names or numbers such as with the Pantone collection, or structured mathematically, as with NCS System, Adobe RGB or sRGB. <P3-S3>  A color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of color interpretation. <P3-S4>  Adding a specific mapping function between a color model and a reference color space establishes within the reference color space a definite "footprint", known as a gamut, and for a given color model this defines a color space. <P3-S5>  For example, Adobe RGB and sRGB are two different absolute color spaces, both based on the RGB color model. <P3-S6>  When defining a color space, the usual reference standard is the CIELAB or CIEXYZ color spaces, which were specifically designed to encompass all colors the average human can see.
