VBA Error 1004 Object Range failed for _Global - vba

Question

I need to make a little VBA Application for a School project.
I recorded a Macro which Resize all Cells and then make them green. After that I select specific Cells and recolor them in white. So the result should be the Excel logo. However when I run the code there is an Error 1004 Range Object failed for _Global.
Code:
Sub Resize()
Columns("A:BZ").ColumnWidth = 2.71
Rows("1:1000").RowHeight = 15
Cells.Select
With Selection.Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.Color = 4485149
.TintAndShade = 0
.PatternTintAndShade = 0
End With
Union(Range( _
"O14:P15,L7:T7,S5:T6,P6:Q6,E38:F47,G46:J47,G42:J43,G38:J39,N38:O39,O40:R41,R38:S39,P42:Q43,O44:R45,N46:O47,R46:S47,W38:X47,Y46:AB47,Y38:AB39,AF38:AK39,AF40:AG47,AH46:AK47,AH42:AK43,AO38:AP47,AQ46:AT47,R6,Y7:AP9,AN10:AP31,Y29:AM31,AF10:AF28,AG24:AM24,Y24:AE24" _
), Range( _
"AG19:AM19,AG14:AM14,Y14:AE14,V4:X33,U5:U32,T12:T25,S14:S23,R16:R21,Q18:Q19,Q28:T32,M26:R27,N24:Q25,O22:P23,L28:P31,H28:K30,F9:G29,H8:J27,K12:K25,L14:L23,M16:M21,N18:N19,K8:T9,M10:R11,N12:Q13" _
)).Select
Cells.Select
With Selection.Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.ThemeColor = xlThemeColorDark1
.TintAndShade = 0
.PatternTintAndShade = 0
End With
End Sub

Answer 1

the string fed to Range must be less then 256 characters, while your first range has just 257... so just shift some characters to the 2nd range
furthermore you're selecting all cells instead of wanted ones
see code:
Option Explicit
Sub Resize()
With Range("A1:BZ1000")
.ColumnWidth = 2.71
.RowHeight = 15
With .Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.Color = 4485149
.TintAndShade = 0
.PatternTintAndShade = 0
End With
End With
With Union(Range( _
"O14:P15,L7:T7,S5:T6,P6:Q6,E38:F47,G46:J47,G42:J43,G38:J39,N38:O39,O40:R41,R38:S39,P42:Q43,O44:R45,N46:O47,R46:S47,W38:X47,Y46:AB47,Y38:AB39,AF38:AK39,AF40:AG47,AH46:AK47,AH42:AK43,AO38:AP47,AQ46:AT47,R6,Y7:AP9,AN10:AP31,Y29:AM31" _
), Range( _
"AF10:AF28,AG24:AM24,Y24:AE24,AG19:AM19,AG14:AM14,Y14:AE14,V4:X33,U5:U32,T12:T25,S14:S23,R16:R21,Q18:Q19,Q28:T32,M26:R27,N24:Q25,O22:P23,L28:P31,H28:K30,F9:G29,H8:J27,K12:K25,L14:L23,M16:M21,N18:N19,K8:T9,M10:R11,N12:Q13" _
)).Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.ThemeColor = xlThemeColorDark1
.TintAndShade = 0
.PatternTintAndShade = 0
End With
End Sub
