Same color is not same color on spriterenderer?

Hello i have i problem with sprtirerender colors. I have the same Color set in the inspector for both gameobjects

But when I am checking the colors in debug.log the colors are not the same anymore

I'm not changing colors in the code anywhere.

Color goColor = gameObject.GetComponentInChildren<SpriteRenderer>().color;
Debug.Log(gameObject.name +" = "+ goColor);
foreach (GameObject g in go)
{
    Color color = g.GetComponentInChildren<SpriteRenderer>().color;
    Debug.Log(g.name + " = " + color);

    //Checkar om färgen stämmer överens med sin connection
    if (color == goColor)
    {
        objectConnection = g;
        Debug.Log(gameObject.name + "Connectade till: " + g);       
    }
    else
    {
        //Debug.Log("Hittade inga matchningar");
    }
}

I think the issue here is the way how this color picker and Color works.

As you can see internally Color is actually stored using float components 0f to 1f.

If you configure the Color via the Hex value or the 0-255 option these values are converted internally and stored as floats.

Then further the implementation of Color.ToString rounds the value for better readability to a precision of 3 decimals.

For visualizing I made a simple

Debug.Log($"rounded: {color}");
Debug.Log($"actual:  {color:G9}");
Debug.Log($"hex:     {ColorUtility.ToHtmlStringRGBA(color)}");

So actually when you configure all colors via the option RGB 0 - 1 for your printed float values you get

for Buttons

rounded: RGBA(0.271, 0.858, 0.712, 1.000)
actual:  RGBA(0.270999998, 0.85799998, 0.712000012, 1)
hex:     45DBB6FF

and for Blockade

rounded: RGBA(0.275, 0.859, 0.714, 1.000)
actual:  RGBA(0.275000006, 0.859000027, 0.713999987, 1)
hex:     46DBB6FF

note especially the last line: While in your screenshot the hex value would be 45DBB5, configuring the colors via the float values actually produces 46DBB6 and 45DBB6 so there is a certain range within the float value might move around a little while the hex / bytes value stays still the same (which makes sense of course since bytes of course have way less precision than a float).

However, Color == Color works with an underlying conversion to Vector4 == Vector4 and the precision for that is 0.00001 which is way more precise than makes sense on a color level.

As a solution to your case you could rather go less precise and simply configure exactly that: The hex value

if(ColorUtility.ToHtmlStringRGBA(color) == ColorUtility.ToHtmlStringRGBA(goColor))
