The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
The solution color of cupric oxide is blue to green.
The pH 10 solution will turn purple because the purple color is stable over a wide pH range. However, if the purple solution contains an indicator that changes color at different pH values, it may undergo a color change.
This solution, if it is pure, is white or colorless.
Red color in acidic solutions and blue color in basic solutions.
Lugol's solution is a brownish-yellow color prior to changing to a dark blue-black color.
Iron (III) chloride solution is typically yellow-brown in color.
Any color is possible.

Colorless
A clear solution indicates that the solution is translucent and light can pass through it without scattering, while a colorless solution means that the solution does not have any color. It is possible for a solution to be clear but still have a color (e.g., a clear blue solution), whereas a colorless solution will appear transparent without any hue.
2 percent bromine solution typically has a reddish-brown color.
A nickel sulfate solution is typically blue-green in color. The exact hue can vary depending on the concentration of the solution.
white color solid and colorless solution
A cobalt sulfate solution is typically blue in color.
Iron III sulfate solution is typically pale yellow in color.
The solution color of cupric oxide is blue to green.
