Trying to Code Random Colors

This code is for a torch effect where I am reandomly changing the intensity and color of a light attached to it.

The problem is that when the colors change it is not a soft light but very intense.

Heres the code.

using UnityEngine;
using System.Collections;

public class LightFlicker : MonoBehaviour {

	[Header("Hi!")]
	public Light lt;

	public float flickerRate;
	public float timer;

	public float intMin;
	public float intMax;
	public float intThreshold;
	public float intStart;

	public float intChange;

	public float colorLerpTime;
	public float colorChangeTime;

	public int gMin;
	public int gMax;

	public Color newColor;
	public Color oldColor;

	// Use this for initialization
	void Start () {

		lt = GetComponent<Light>();

		intStart = lt.intensity;
		intMax = intStart + intThreshold;
		intMin = intStart - intThreshold;

		lt.color = Color.red;
		oldColor = Color.yellow;
	
		InvokeRepeating("ColorChange", 1, colorChangeTime * Time.deltaTime);
	}

	void ColorChange()
	{

		newColor = new Color (255,Random.Range(gMin,gMax),0,255);

		lt.color = Color.Lerp(oldColor, newColor, colorLerpTime * Time.deltaTime);

		oldColor = newColor;

	}
	
	// Update is called once per frame
	void Update () {

		timer -= Time.deltaTime;

		if(timer < 0)
		{
			if( 0.5f < Random.value)
			{
				lt.intensity -= intChange;
			}
			if(0.5f > Random.value)
			{
				lt.intensity += intChange;
			}
			if(intMax < lt.intensity)
			{
				lt.intensity = intStart;
			}
			if(intMin > lt.intensity)
			{
				lt.intensity = intStart;
			}

			timer = flickerRate;
		}

	
	}
}

Here is a picture of the problem, notice how low the intensity is!

Its hard to see here but the RBGA here is:

R: 65025
G: 49456
B: 0
A: 255

Obviously the R and G are no good but not really sure why?

The Unity 1 components are values ranging from 0 to 1.
