Yes, LED profiles themselves don't produce any light, but they are used in conjunction with LED strips, which can produce colored light. If you want your LED profiles to produce colored light, you should use RGB (Red, Green, Blue) or RGBW (Red, Green, Blue, White) LED strips. These types of LED strips are capable of producing a wide range of colors.
RGB and RGBW LED strips consist of multiple LEDs, each of which can produce red, green, or blue light. By varying the intensity of these primary colors, the strip can create virtually any color in the spectrum. An RGBW strip adds an additional white LED for a wider range of color and brightness options.
To control the color output of an RGB or RGBW LED strip, you'll need an appropriate controller. This could be a handheld remote, a wall-mounted touch panel, or even a smartphone app if your LED strip system is smart home compatible. Some controllers also allow you to set dynamic lighting effects, such as color cycling or pulsing to music.
Remember that not all LED profiles might be suitable for RGB or RGBW strips, especially if the strips are wider or require more ventilation than standard strips. Always check the specifications of the LED profile before installing RGB or RGBW LED strips.
