Yes, choosing a solid color over an image reduces resource usage in Windows.

For static images, the same resources are applied. Only animated wallpapers affect resource consumption.
Only during startup, after the image is loaded, it becomes less demanding on resources.
Once upon a time, achieving solid image quality on a home console required powerful "Blast Processing."
The system likely stores and prepares images for quick access. A high-resolution 1080p file would be around 6MB, while a 4K version could reach 24MB. Over two decades ago, such sizes would have been noticeable, though monitors were less powerful. Back then, using smaller tiled images was common to save resources while still allowing customization.
In technical terms, yes. Back in 1995, the CPU handled all drawing tasks. Graphics cards or accelerators were costly and mainly for gamers. Integrated graphics inside the CPU weren't available then—they just displayed images created by the CPU, which was quite unreliable. PCs were expensive, so the interface always looked simple. Now, with GPU rendering, even a basic GPU can handle wallpapers without draining your limited RAM or CPU resources.
Looking at the number of CPUs I have... I usually opt for a solid screen background to conserve memory, rather than focusing on CPU speed.
