Extract text between two patterns excluding patterns

Consider the output of java -jar plantuml.jar -language:

;type
;26
abstract
actor

............................

;color
;147
AliceBlue
AntiqueWhite
Aqua
Aquamarine
............................
Wheat
White
WhiteSmoke
Yellow
YellowGreen

;EOF

I need to extract colors from this text without surrounding strings. I have read several articles and Q&As and did not found answer. Here i found the most suitable answer. 

$ java -jar plantuml.jar -language | sed -n '/\;color/,/\n\n/{/color/!{/\n\n/!p}}'
;147
AliceBlue
AntiqueWhite
Aqua
Aquamarine
Azure
Beige
Bisque
....................
Teal
Thistle
Tomato
Turquoise
Violet
Wheat
White
WhiteSmoke
Yellow
YellowGreen

;EOF

There is a small nuance: ;147 could be any other value and EOF could be changed at any time to something other. I tried sed -n '/\;color\s*\;\d*/,/\n\n/, but it returns nothing. Please help me to achieve the next result:

AliceBlue
AntiqueWhite
Aqua
Aquamarine
Azure
Beige
Bisque
....................
Teal
Thistle
Tomato
Turquoise
Violet
Wheat
White
WhiteSmoke
Yellow
YellowGreen

With sed to delete all lines between patterns not starting with ;:

sed -n '/^;color/,/^;EOF/{/;/d;p}' file

To delete last blank line:

sed -n '/^;color/,/^;EOF/{/;/d;/^$/d;p}' file

or with GNU sed:

sed -n '/^;color/,/^;EOF/{/^;\|^$/d;p}' file

It SOUNDS like all you need is:

awk '/^;/{if (/[[:alpha:]]/) f=(/color/?1:0); next} f'
