Change color in chart series (Chart Controls)?

Question

Does anyone know if it's possible to change the color within a series in Microsoft Chart Controls?  My data is X = test time and Y = response time using a column graph.  Currently when the test to collect response time fails it does not
record a numerical value and when graphed it appears as though the response time was minimal.  I want to make it stand out when a failure occurs, for example to draw a large column and change the color to red (other values are in blue).
I don't have much experience using Chart Controls yet.  I know you can use an alternate color with a different series of data but it doesn't appear you can change it from within. 
This is my chart series (when a test fails, the response matches "" and not $NULL):
[void]$chart1.Series.Add("ResponseTime")
$chart1.Series["ResponseTime"].ChartType = "Line"
$chart1.Series["ResponseTime"].BorderWidth  = 1
$chart1.Series["ResponseTime"].IsVisibleInLegend = $true
$chart1.Series["ResponseTime"].chartarea = "ChartArea1"
$chart1.Series["ResponseTime"].color = "#0404B4"
$DATA | ForEach-Object {
If ($_.RESPONSE_MS -eq "") {
$chart1.Series["ResponseTime"].Points.addxy("FAIL",9999)
Else {
$chart1.Series["ResponseTime"].Points.addxy( $_.TIME.Remove(5) , ($_.RESPONSE_MS)) }
I tried changing the color within the if/else but the first .color value it picks up will be used throughout.

Hi Tickermcse76,
To create a new line chart, please refer to this script:
function New-Chart
param ([int]$width,[int]$height,[int]$left,[int]$top,$chartTitle)
# create chart object
$global:Chart = New-object System.Windows.Forms.DataVisualization.Charting.Chart
$global:Chart.Width = $width
$global:Chart.Height = $height
$global:Chart.Left = $left
$global:Chart.Top = $top
# create a chartarea to draw on and add to chart
$chartArea = New-Object System.Windows.Forms.DataVisualization.Charting.ChartArea
$global:chart.ChartAreas.Add($chartArea)
[void]$global:Chart.Titles.Add($chartTitle)
# change chart area colour
$global:Chart.BackColor = [System.Drawing.Color]::Transparent
} #New-Chart
New-Chart -width $width -height $height -left $left -top $top -chartTile $chartTitle
[void]$global:Chart.Series.Add("Data")
# $global:Chart.Series["Data"].Points.AddXY($(get-date), $($ht.Values))
$global:Chart.Series["Data"].Points.DataBindXY($ht.Keys,$ht.Values)
#$global:Chart.Series["Data"].XValueType = [System.Windows.Forms.DataVisualization.Charting.ChartValueType]::Time
#$global:Chart.chartAreas[0].AxisX.LabelStyle.Format = "hh:mm:ss"
#$global:Chart.chartAreas[0].AxisX.LabelStyle.Interval = 1
#$global:Chart.chartAreas[0].AxisX.LabelStyle.IntervalType = [System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType]::Seconds
$global:Chart.Series["Data"].ChartType = [System.Windows.Forms.DataVisualization.Charting.SeriesChartType]::Line
#$global:chart.Series["Data"].IsValueShownAsLabel = $false
