First of all, thank you @ocornut for your fantastic work.

I found a bug on ColorPickers (both RGB and RGBA versions).

With ImGui v1.89.2, when I do this :

static float aaa[4] = { 0, 0, 0, 0 };
static float bbb[4] = { 0, 0, 0, 0 };

if (ImGui::Begin("window aaa"))
  ImGui::ColorPicker4("aaa", aaa);
ImGui::End();

if (ImGui::Begin("window bbb"))
  ImGui::ColorPicker4("bbb", bbb);
ImGui::End();

The ColorPickers seem to interfere with each other when their RGB values are the same full black or full white (all 0 or all 255).
If I use the vertical color bar on the right side of aaa, then the aspect of bbb will also change.

Thank you for reporting. We have code trying to preserve HSV properties for lossy round-trips via encoded u32 value and it seems it has a problem here.
