Efficiently navigating arrays and selected strings - arrays

Question

I am a noob playing around with actionscript but i feel this question is a basic coding questionMy project is similar to this picture.
I have four quadrant areas (Red, blue, yellow, and green) that I am adding text buttons to each area with a single word in each button. There are 16 words in each section that are added from 4 arrays that have the preset words (redWordArray, greenWordArray, yellowWordArray, blueWordArray). When clicked, the text button glows using a glow filter and the word gets added to another array for data collecting. For instance, a red word when clicked gets added to a red array (redChosenArray). When the word is clicked again, it removes the glow filter and is removed from the chosen array.
I am finding that my performance is slow and I am wondering if I am adding and deleting words correctly and efficiently. These are my functions for adding the glow filters and the selected word to the array. I would love your insights for best coding practices as I am sure it is a mess!
Thank you!
function selectWord(event:MouseEvent):void
{
var tempWord:String = event.currentTarget.mood.text;
var tempArray:Array;
if (event.currentTarget.clicked == false)
{
event.currentTarget.filters = filterArray;
event.currentTarget.clicked = true;
tempArray = addToArray(tempWord)
tempArray.push(tempWord);
trace(redChosen);
trace(blueChosen);
trace(yellowChosen);
trace(greenChosen);
trace("");
}else if(event.currentTarget.clicked == true)
{
event.currentTarget.filters = emptyFilterArray;
event.currentTarget.clicked = false;
removeMoodWord(tempWord);
trace(redChosen);
trace(blueChosen);
trace(yellowChosen);
trace(greenChosen);
trace("");
}
}
function addToArray(moodWord:String):Array
{
var wordFound:Boolean = false;
var allWords:int = 16;
var chosenArray:Array;
while (!wordFound)
{
for (var h:int = 0; h < allWords; h++)
{
if (moodWord == redWords[h])
{
chosenArray = redChosen;
wordFound = true;
}else if (moodWord == yellowWords[h])
{
chosenArray = yellowChosen
wordFound = true;
}else if (moodWord == greenWords[h])
{
chosenArray = greenChosen
wordFound = true;
}else if (moodWord == blueWords[h])
{
chosenArray = blueChosen
wordFound = true;
}
}
}
return chosenArray;
}
function removeMoodWord(moodWord:String):void
{
if (redChosen.indexOf(moodWord) >= 0)
{
redChosen.splice(redChosen.indexOf(moodWord), 1);
}else if (blueChosen.indexOf(moodWord) >= 0)
{
blueChosen.splice(blueChosen.indexOf(moodWord), 1);
}else if (yellowChosen.indexOf(moodWord) >= 0)
{
yellowChosen.splice(yellowChosen.indexOf(moodWord), 1);
}else if (greenChosen.indexOf(moodWord) >= 0)
{
greenChosen.splice(greenChosen.indexOf(moodWord), 1);
}
