On the RGBW led strip, in addition to RGB, you get one extra diode which is Warm White. That warm white diode has a Kelvin temperature of 2400 which means it has a yellowish look giving it a warmer, softer, candle like look (see photo below).
RGB LEDs can produce white light by mixing the primary red, green and blue lights together in theory. But the mixture includes blending and diffusion of colors, creating factitious white light. This kind of white light seems to be covered with fog.
New LED technology from Integral LED allows you to switch between 3000K (Warm), 4000K (Cool White ) and 5000K (Daylight).
Beside the red, green, and blue LED chips, there is a white LED chip in RGBW LEDs. Although, RGB LEDs create a color close to white, it cannot create a pure white tone. An extra white LED chip allows to obtain more real and more bright white light.
According to this article, R255, G197 and B143 create a color similar to warm white.
Usually, RGB lighting won't make your PC hotter. But if you have many RGB LEDs, it can increase your PC's temperature slightly. So you should turn off RGB lights when they are not needed. You can also lower their brightness to reduce heat generation.
How does color mixing apply to LEDS and Lighting An RGB LED is an LED module that can produce almost any color using these three primary additive colors: Red, Green and Blue. The simplest version of an RGB LED has a combination of 3 separate light-emitting diodes in one package, housed under a clear protective lens.
If all you're after are basic RGB colours with no requirement for a proper white then basic RGB LED strip is generally more cost effective, however if you do need white (for example for task lighting) then RGB+W is a better bet.
The majority of LEDs are produced to be either 2700k, 2800k, 3000k, 4000k or 5000k. 2700-3000k being warm, 4000-5000k being cool. Some people do have some misconceptions about LEDs. They believe LEDs provide a cool unflattering light.
Unlike incandescent lamps, LEDs are not inherently white light sources. Instead, LEDs emit nearly monochromatic light, making them highly efficient for colored light applications such as traffic lights and exit signs. However, to be used as a general light source, white light is needed.
Information about White / #ffffff
In a RGB color space (made from three colored lights for red, green, and blue), hex #ffffff is made of 100% red, 100% green and 100% blue.

Introduction: RGB LED Temperature Indicator
In this project the LED will change colours from blue to cyan to green to yellow to pink to red, depending on the temperature of the surrounding environment, with blue indication very cold and red indication very hot.
While a backlit RGB gaming monitor is primarily a cosmetic effect, it can also have an effect on the gaming experience in unexpected ways. From improving contrast to reducing eye strain, the RGB LEDs on the back of gaming monitors have a practical function.
By mixing light of these 3 base colors, you could create any color perception. But such a color set does not exist. RGB does a pretty good job of covering a large part of the color gamut, but not all (RGB fails at saturated cyan and yellow, for example).
For example, if we want to produce a yellow color, we combine red and green colors. So, we need to switch the red and the green colors simultaneously. It can be represented as RGB=[1 1 0] in the program.
DisadvantagesRGB values are commonly not transferable between devices.Not perceptually uniform.Not perfect for the identification of colors.Difficult to determine specific color.The difference between colors is not linear.
“The advantage [of RGB] being that rather than just being set to one color from the factory, you get 16.8 million colors to choose from, so it's really up to your own imagination. Then, through software, you can then specify those colors per key, in zones or per game or application.
Nowadays, LED lights are available in 3 tones that generate a much wider breadth of light, reaching across infrared, ultraviolet, and visible wavelengths: cool, natural, and warm.
LED bulbs oﬀer light in a range of color temperatures, it's what makes light feel 'warm' or 'cool'. A lower color temperature produces a warmer, more relaxing light. A higher color temperature emits a cooler, more refreshing light.
When it comes to buying LED lamps, the colour ranges you get start at warm white, which is a more yellow colour, through to cool white, a more 'pure white' colour, through to daylight, which is more light a white with a blue hue.
Color temperature is measured in Kelvin (K), and there are three common ranges: Warm Light (2700K-3000K); Cool White (3000K-5000K), and Daylight (5000K-6500K). Warm Light resembles the color of an incandescent; looking orange or yellow. Cool White ranges from Yellow-White (3000K) to White (4000K) to Blue-White (5000K).
RGB LEDs cannot produce pure white light because there is no such thing. Nothing can produce pure white light. White is the experience of all colour receptors firing off at the same time… or a subset firing off too much. Either way, it is not it's own colour.
Conclusion. In summary, we can say that LED lights with only white LEDs have their strengths in energy efficiency but RGB lamps definitely score in terms of color accentuation.
