    Why this gloomEffect glsl code output only black & white image?

    the code below produce only black & white output any idea why ?

    Code glsl:
    varying vec4 TEX0;
    vec4 _ret_0;
    vec3 _TMP4;
    float _TMP3;
    vec3 _x0014;
    vec3 _TMP15;
    float _grey0022;
    float _grey0028;
    vec3 _TMP35;
    uniform float _GloomIntensity;
    uniform float _BaseIntensity;
    uniform float _GloomSaturation;
    uniform float _BaseSaturation;
    uniform sampler2D _Input;
    void main()
    {
        vec4 _color1;
        vec3 _base;
        vec3 _gloom;
        vec3 _TMP10;
        _color1 = texture2D(_Input, TEX0.xy);
        _base = 1.0 - _color1.xyz/_color1.w;
        _x0014 = (_base - 2.50000000E-001)/7.50000000E-001;
        _TMP4 = min(vec3( 1.0, 1.0, 1.0), _x0014);
        _TMP15 = max(vec3( 0.0, 0.0, 0.0), _TMP4);
        _grey0022 = dot(_TMP15, vec3( 3.00000012E-001, 5.89999974E-001, 1.09999999E-001));
        _TMP3 = _grey0022 + _GloomSaturation*(_TMP15.x - _grey0022);
        _gloom = vec3(_TMP3, _TMP3, _TMP3)*_GloomIntensity;
        _grey0028 = dot(_base, vec3( 3.00000012E-001, 5.89999974E-001, 1.09999999E-001));
        _TMP3 = _grey0028 + _BaseSaturation*(_base.x - _grey0028);
        _base = vec3(_TMP3, _TMP3, _TMP3)*_BaseIntensity;
        _TMP4 = min(vec3( 1.0, 1.0, 1.0), _gloom);
        _TMP35 = max(vec3( 0.0, 0.0, 0.0), _TMP4);
        _base = _base*(1.0 - _TMP35);
        _TMP10 = (1.0 - (_base + _gloom))*_color1.w;
        _ret_0 = vec4(_TMP10.x, _TMP10.y, _TMP10.z, _color1.w);
        gl_FragColor = _ret_0;
    }
