Result of the test is:

Invalid alpha value specifier 'foo' in 'red at foo'
Invalid alpha value specifier '' in 'red@'
Invalid alpha value specifier '0xfff' in 'red at 0xfff'
red at 0xf -> R(255) G(0) B(0) A(15)
red at 2 -> R(255) G(0) B(0) A(2)
red at 0.1 -> R(255) G(0) B(0) A(25)
Invalid alpha value specifier '-1' in 'red at -1'
red at 0.5 -> R(255) G(0) B(0) A(127)
red at 1.0 -> R(255) G(0) B(0) A(255)
Invalid alpha value specifier '256' in 'red at 256'
Invalid alpha value specifier '10foo' in 'red at 10foo'
Invalid alpha value specifier '-1.0' in 'red at -1.0'
red at -0.0 -> R(255) G(0) B(0) A(0)
