IT cosmetics有买一送一，可以买眼部遮瑕，遮黑眼圈效果很不错

好几个商品都是买一送一 https://www.itcosmetics.com/online-offers/limited-time-promotions
可以买眼部遮瑕，遮黑眼圈效果很绝，色号30.5 Tan三文鱼色，质地轻薄而且很滋润，不会卡纹 https://www.itcosmetics.com/makeup/face-makeup/under-eye-concealer/bye-bye-under-eye-full-coverage-anti-aging-waterproof-concealer/ITC_0005.html
还有这个粉底也好用，很服帖 https://www.itcosmetics.com/makeup/face-makeup/foundation/your-skin-but-better-foundation-skincare/ITC_886.html

请问遮泪沟哪个色号好啊？
