Dim oHtml As HTMLDocument
Dim tags As Object
Dim HTMLtags As IHTMLElementCollection
Dim HTMLtag As IHTMLElement
With oIE
.Visible = True
.navigate "https://www.gdax.com/trade/LTC-EUR"
Do Until .readyState = READYSTATE_COMPLETE: Loop
Set oHtml = .document
End With
'this is needed to wait until the page is totally loaded
Do: Set tags = oHtml.getElementsByClassName("OrderBookPanel_text_3fH-g")(0): DoEvents: Loop While tags Is Nothing
'getting the element that it is about
Do: Set HTMLtags = oHtml.getElementsByClassName("OrderForm_toggle_31S34"): DoEvents: Loop While HTMLtags.Length = 0
Set HTMLtag = HTMLtags(0).Children(0)
Debug.Print HTMLtag.innerText
'this is the problem
Debug.Print HTMLtag.Style.backgroundColor
End Sub

Try the below code:
Sub Colorfinder()
With CreateObject("InternetExplorer.Application")
.Visible = True
.navigate "https://www.gdax.com/trade/LTC-EUR"
Do While .Busy Or .readyState < 4: DoEvents: Loop
With .Document
Do While .getElementsByClassName("OrderBookPanel_text_3fH-g").Length = 0: DoEvents: Loop
Do While .getElementsByClassName("OrderForm_toggle_31S34").Length = 0: DoEvents: Loop
With .parentWindow
.execScript "var e = document.getElementsByClassName('OrderForm_toggle_31S34')[0].children[0];"
.execScript "e.style.backgroundColor = window.getComputedStyle(e,null).getPropertyValue('background-color');"
End With
Debug.Print .getElementsByClassName("OrderForm_toggle_31S34")(0).Children(0).Style.backgroundColor ' rgb(77, 165, 60)
End With
End With
End Sub
.execScript executes JScript code within HTML document, that is why syntax uses var, ', [] and ;, etc., variable e is the target node declared in the document scope, and it's actual computed background value just put into .backgroundColor property. Using .execScript is the only way I found to get to window.getComputedStyle method, which actually do the job.

Is this really something that needs to be automated?
The background-color of the BUY button is:
(Click for more about #4da53c Strong Sap Green.)
Right-click any element on a web page and choose Inpsect Element to find the color under the style properties (specific location depends on your browser).
Or, use a color detection utility such as:
Instant Eyedropper which runs in the background. You click the icon in your system tray and then any spot on your screen to identify the color of the pixel.
Firefox add-on: colorPicker same idea, but a plug-in.
Others are available for other browsers, and there are also websites that will identify colors from uploaded images, URLs, entire website color schemes, etc.
