Short description of error
After entering the hexcode B3FF4A into a shader's color field, the vertical Value Slider is at 0.5, and doesn't match it's numerical value of 1.000 in the HSV Value text field. Dragging the vertical Value Slider up causes the Value in the horizontal slider to go beyond 1.000. Dragging the vertical Value slider up also automatically changes the Hue + Saturation values of the color.

Additionally, after entering the same B3FF4A in the hex field, the color's numerical Alpha value is 1.000, but the horizontal Alpha slider is at what is normally 0.5. Dragging the slider to the right causes the Alpha value to go up to 2.000.

Exact steps for others to reproduce the error

  1. Load default startup file
  2. Enter the shading workspace by selecting it from the top of the window
  3. Change the Base Color of the default Principled BSDF shader by pasting this hexcode: B3FF4A
  4. Immediately after pressing enter, the vertical Value Slider and the horizontal Alpha slider will not match their respective numerical values in their number fields.
