教室裡 色彩學講著光的秘密

紅黃藍的三原色 描繪世界的軌跡

你的黃色 曾是我心底唯一的明亮

但藍色闖入 你的光芒變了模樣

黃色加上藍 成了一抹冷冷的綠

黑色的我 只能看著不再靠近你

想變成紫色 想成為你的互補

卻發現紅才是你缺少的那一束

你成了綠色 我成了灰色

黑與白混成 最沉默的顏色

曾經鮮明的對比 如今模糊不清

這段故事的結尾 是孤單的透明

你成了綠色 我成了灰色

愛的顏色褪去 只剩下無聲告別

我們的距離 從色彩變成裂痕

這段愛情的終點 是消失的餘痕

你曾是 我世界裡最溫暖的陽光

你的黃色 讓黑夜有了柔和的方向

但藍色來了 你的眼神不再明亮

你成了綠 我卻陷在自己的荒涼

紅與綠相對 是色盤上的默契

而我的黑 只能被遺忘在孤寂

試圖加入白 改變自己模樣

結果卻是灰 無法再點亮

你成了綠色 我成了灰色

黑與白混成 最沉默的顏色

曾經鮮明的對比 如今模糊不清

這段故事的結尾 是孤單的透明

你成了綠色 我成了灰色

愛的顏色褪去 只剩下無聲告別

我們的距離 從色彩變成裂痕

這段愛情的終點 是消失的餘痕

我以為變成紫色 你會再注意我

卻忘了藍早已改變你的執著

黑色的妥協 換不來你的片刻

灰色的結果 是我的唯一選擇

綠色 灰色 分離的顏色

你不再回頭 我再也不是什麼

綠色 灰色 愛變成裂痕

這段故事的結尾 只剩下消沉

綠色 灰色 兩個世界的錯

不管我怎麼改變 都無法重來過

教室裡 色彩學還在繼續

紅黃藍的定律 卻改變不了結局

你的顏色 早已遠去不再熟悉

而我的世界 只剩灰色的痕跡

In the classroom, color theory reveals the secrets of light,

Red, yellow, and blue—the primary hues trace the world's design.

Your yellow was once the sole brightness in my heart,

But when blue intruded, your light took on a different part.

Yellow combined with blue became a cold shade of green,

While black, like me, could only watch, never draw close again.

I longed to turn purple, to complement you,

Yet realized it was red you truly needed in view.

You became green, I turned gray,

Black and white blended into the quietest shade.

Once vivid contrasts now blurred and unclear,

The ending to this story is lonely and sheer.

You became green, I turned gray,

The colors of love faded, leaving a silent farewell.

Our distance transformed from hues into cracks,

The end of this love is a trace that won’t come back.

You once were the warmest sunshine in my world,

Your yellow gave the night a soft direction, unfurled.

But blue arrived, and your gaze lost its glow,

You turned to green, while I drowned in my desolate shadow.

Red and green—opposites, yet in harmony on the wheel,

But my black was destined to be forgotten, never healed.

I tried adding white to change my form,

But gray was all I became, never reborn.

You became green, I turned gray,

Black and white blended into the quietest shade.

Once vivid contrasts now blurred and unclear,

The ending to this story is lonely and sheer.

You became green, I turned gray,

The colors of love faded, leaving a silent farewell.

Our distance transformed from hues into cracks,

The end of this love is a trace that won’t come back.

I thought turning purple might make you see me again,

But I forgot how blue had already altered your obsession.

Black’s compromises could never earn your affection,

And gray was the only result of my concession.

Green and gray, colors of separation,

You never looked back, and I became nothing but desolation.

Green and gray, love fractured into division,

The end of this story is left in silent attrition.

Green and gray, two worlds gone astray,

No matter how I change, we cannot relive yesterday.

In the classroom, color theory carries on,

The rules of red, yellow, and blue can't alter what’s gone.

Your color has drifted, no longer familiar to me,

And my world is left with only traces of gray to see.
