Changing text color at runtime always white...

Question

I'm trying to change text to a specific shade by using this code:

 timeColor = new Color (68f, 144f, 233f, 1f);
 timerDisplay.gameObject.GetComponent<Text> ().color = timeColor;

And have also tried this:

 timeColor = new Color (68f, 144f, 233f, 1f);
 timerDisplay.color = timeColor

They both turn my text to white for some reason. Any ideas why?

The RGB values of a Color need to be float values between 0-1. (You can calculate these values by dividing by 255.)

If you want to use byte values, you need to use Color32 https://docs.unity3d.com/ScriptReference/Color32.html

 timeColor = new Color32(68, 144, 233, 255);

color is not a property of the text itself, but of the UI element that contains it. What you want is timerDisplay.font.material.color

And yeah, as the above answer says you need 0-1 values.

Thanks guys, that makes sense. So do I need to add a material to the font? Because even with these changes, my font is not changing (in this case to red).

                 if (secs >= 0) {
             if (secs <= 10) {
                 timeColor = new Color32 (255, 70, 57, 255);
                 Debug.Log ("red");
                 if (interval > tics && tics > 0) {
                     source.PlayOneShot (alarm);
                     interval--;
                 }
             } else {
                 timeColor = new Color32 (66, 154, 255, 255);
                 Debug.Log ("blue");
             }
             //timerDisplay.color = new Color(68f, 144f, 233f, 1f);
             timerDisplay.font.material.color = timeColor;
             timerDisplay.text = "Time: " + secs;
         }

You can use color attribute to provide color for the text.

It can be done by two ways -> using the color static attributes and color class constructor.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class ColorDemo : MonoBehaviour {
 
     [SerializeField]
     Text infoText;
 
     void Start () {
        infoText.text = "Hello World";
        infoText.color = Color.red; //Red color using Color class
        //Red color using hex value. (255,0,0) => 255/255, 0/255, 0/255) => (1,0,0)
        infoText.color = new Color(1f, 0f, 0f); 
        // Color with opacity value. 1 means opaque and 0 means transparent.
        infoText.color = new Color(1f, 0f, 0f, 0.5f); 
     }
 }
